This study is grounded in CTT, the central framework within relationship marketing that conceptualises trust and commitment as the key mediators through which relationship-building efforts influence relational continuity (Morgan & Hunt 1994). Recent analyses reaffirm its relevance across contemporary service environments and call for renewed testing in digitally transformed contexts (Badrinarayanan & Ramachandran 2024; Morgan & Feng 2024). The theory suggests that satisfaction strengthens trust, which fosters commitment, relationships consistently validated in traditional service settings.

Digital transformation introduces system-based trust cues, such as interface reliability, data security and process transparency, that may complement or partially substitute interpersonal cues (Belanche, Casaló & Flavián 2021; Kim, Connerton & Park 2022). This raises theoretical uncertainty about whether digitalised service encounters weaken, strengthen or leave unchanged the classical satisfaction-trust-commitment mechanism. The role of perceived service innovation further complicates this relational structure. Innovation may enhance functional and experiential evaluations, yet its ability to condition relational pathways remains unclear. Consequently, the conceptual framework integrates satisfaction, trust and commitment within a CTT lens while examining perceived service innovation as a potential moderating variable.

This study aimed to examine whether the satisfaction-trust-commitment mechanism remains robust in digitally enabled automotive dealership environments and to assess whether perceived service innovation moderates the trust-commitment relationship. The research objectives included:

The literature review and hypotheses are discussed next, followed by the research design and methods. Thereafter, the measurement and structural model results are reported, with the findings, theoretical contributions, managerial implications and future research directions then being outlined. Finally, the study’s conclusion and limitations are acknowledged.

Commitment-trust theory remains one of the most influential frameworks for explaining why customers maintain long-term relationships with firms (Brown et al. 2019; Morgan & Hunt 1994). Commitment-trust theory proposes that satisfaction strengthens trust, which strengthens commitment, forming a sequential mechanism that underpins relationship quality and relational continuity. Recent scholarship confirms the enduring relevance of this framework in contemporary sales and service environments (Badrinarayanan & Ramachandran 2024; Morgan & Feng 2024) while also calling for renewed scrutiny of its assumptions as digital transformation reshapes customer-firm interaction patterns (Brown et al. 2019).

Digital transformation fundamentally reconfigures the informational, transactional and relational architecture of service encounters (Verhoef et al. 2021). In automotive retail specifically, industry reports indicate that customers now complete a substantial portion of their decision journey online before visiting a dealership, using digital channels to research models, compare prices, configure vehicles and obtain quotations (Terason et al. 2025; Walker & Proff 2024). This shifts the locus of satisfaction formation from purely interpersonal encounters to hybrid journeys in which system-based cues, such as website functionality, information accuracy and booking reliability, play a central role. Empirical work across banking, retail and hospitality similarly shows that digital interfaces shape satisfaction and relational outcomes via perceived transparency, convenience and control (Belanche, Casaló & Flavián 2019; Belanche et al. 2021; Steinhoff et al. 2019).

These developments suggest that classical relationship quality constructs, such as satisfaction, trust and commitment, originally conceptualised in high-contact, salesperson-dominated settings (Brown et al. 2019; Mpinganjira, Roberts-Lombard & Svensson 2017), must be re-examined in technologically mediated contexts. Recent research on digital customer journeys and omnichannel service environments similarly emphasises that relational constructs developed in traditional service settings require re-evaluation as customers increasingly interact with firms through hybrid digital–physical touchpoints (Becker & Jaakkola 2020; De Keyser et al. 2023; Dong & Verhoef 2024). In digitally enabled dealerships, customers integrate interpersonal and system-based cues when forming trust judgements (Chauhan, Akhtar & Gupta 2022; Dong & Verhoef 2024). The system-based trust theory proposes that when customers cannot directly observe a firm’s motives or internal processes, they rely on structural assurances, including secure systems, reliable procedures and situational normality such as professional interfaces and standardised processes, to infer trustworthiness (McKnight, Choudhury & Kacmar 2002). Contemporary studies on digital trust similarly show that customers rely on technological infrastructure, platform transparency and system reliability as signals of institutional trustworthiness in technology-enabled service environments (Becker & Jaakkola 2020; Huang & Rust 2023). Digital platforms provide structural assurances through secure payment gateways, traceable communications and transparent information displays, suggesting that CTT’s mechanisms might operate through a broader set of cues in hybrid journeys than originally envisaged. Against this backdrop, this study applied CTT as the primary theoretical lens to examine how satisfaction and trust shape commitment in digitally enabled automotive dealership environments and to test whether these mechanisms remain robust under conditions of technological mediation.

Service innovation has become central to the digital transformation efforts of firms, particularly in environments where customers interact across multiple technology-enabled touchpoints. It refers to new or enhanced service processes, interfaces, and offerings that improve the service experience, often within broader digitally connected ecosystems (Lusch & Nambisan 2015; Wagner, Schramm-Klein & Steinmann 2020; Witell et al. 2016). In automotive retail, such innovations include online configurators, virtual showrooms, integrated booking platforms, automated service reminders and AI-based communication tools (Miguel et al. 2022; Wan et al. 2023).

However, empirical findings about the relational implications of service innovation remain fragmented. Some studies indicate that innovation can signal competence, responsiveness and modernity, thereby enhancing CS and loyalty intentions (Mahmoud et al. 2018; Tai et al. 2021). Others suggest that innovation primarily improves functional outcomes, such as convenience and process efficiency, without fundamentally altering deeper relational constructs such as trust and commitment (Pansari & Kumar 2017; Steinhoff et al. 2019). Very few studies explicitly examine whether service innovation interacts with established relationship quality mechanisms or influences the satisfaction-trust-commitment pathway central to CTT.

To clarify these theoretical ambiguities and locate this study within broader service innovation literature, a structured synthesis of key contributions across A- and strong B-rated journals was undertaken. Table 1 summarises leading conceptual and empirical work on service innovation, service ecosystems and relationship quality.

Collectively, the studies summarised in Table 1 reveal that service innovation research, even within reputable A- and strong B-rated outlets, remains theoretically fragmented and insufficiently linked to the relational quality mechanisms that underpin long-term customer-firm relationships. Many studies demonstrate that service innovation enhances satisfaction, value or loyalty within various industries, such as banking, hospitality, telecommunications and automated retail. However, few incorporate trust or commitment as distinct constructs and even fewer examine how innovation interacts with the satisfaction-trust-commitment sequence foundational to relationship marketing and CTT.

Moreover, the reviewed work rarely examines high-involvement hybrid digital–physical contexts. Automotive dealerships represent such environments, where customers face substantial financial, performance and safety risks and where relationships typically extend beyond the initial transaction to include ongoing maintenance and after-sales service. None of the studies specifically investigates service innovation within digitally enabled automotive dealerships, nor assesses whether innovation conditions the trust-commitment pathway predicted by CTT. This omission highlights a clear conceptual and empirical gap. This study addressed this gap by re-examining the satisfaction-trust-commitment mechanism in digitally transformed dealership ecosystems and evaluated perceived service innovation as a potential moderator of the trust-commitment relationship. Building on this foundation, the following subsections develop hypotheses for the tested model.

Digitalisation has blurred the boundary between transactional efficiency and relational quality in service settings (Becker & Jaakkola 2020; Kamalaldin et al. 2020). Historically, automotive dealership relationships were shaped primarily by salesperson expertise, interpersonal warmth and the quality of after-sales engagement (Balinado et al. 2021; Van Tonder et al. 2017). These interpersonal drivers remain important, yet digital touchpoints now play an equally critical role by providing rapid access to information, self-service convenience and greater transparency around pricing and availability (De Keyser et al. 2023; Grewal, Roggeveen & Nordfält 2017; Verhoef et al. 2021). Recent research on digitally integrated service ecosystems further suggests that technology-enabled interfaces increasingly complement interpersonal interactions by enhancing accessibility, information transparency and service responsiveness (Becker & Jaakkola 2020; Hollebeek, Sprott & Andreassen 2022).

Therefore, in digitally enabled dealerships, CS and trust emerge from evaluations of an integrated journey rather than a single encounter. Website performance, information accuracy, online booking reliability, real-time communication, showroom experience and service quality all contribute to relational judgements. Contemporary customer journey research similarly emphasises that value creation occurs across interconnected digital and physical touchpoints that collectively shape customer perceptions of reliability, convenience and relational quality (Becker & Jaakkola 2020; De Keyser et al. 2023). This hybrid reality suggests that CTT’s relational constructs are not replaced by digitalisation but are recontextualised within multichannel service ecosystems. Whether the psychological linkages identified by CTT function in the same way within these digital–physical journeys remains an open empirical question.

Customer satisfaction reflects a cumulative evaluation of a dealership’s performance relative to expectations across multiple touchpoints, including perceptions of process quality, information quality and interpersonal interactions (Oliver 1980). In hybrid digital-physical contexts, satisfaction is influenced not only by face-to-face encounters but also by the ease of navigating online interfaces, the coherence of cross-channel experiences and the reliability of digital tools (Pansari & Kumar 2017; Van Phuong et al. 2024).

Consequently, in digitally enabled dealerships, satisfaction emerges from evaluations that span website functionality, information completeness, quotation processes, booking systems, in-dealership treatment and after-sales service. Each touchpoint generates cues about organisational competence and customer centricity. The system-based trust theory posits that when customers cannot directly observe the intentions of a firm, they rely on structural assurances, for example, secure systems, professional interfaces and standardised procedures and situational normality to infer trustworthiness (Al-Kfairy et al. 2023; Geebren 2025; McKnight et al. 2002). Digital channels provide such structural assurances through secure communication, traceable interactions and transparent information displays. Accordingly, high satisfaction with hybrid service journeys should strengthen perceptions of reliability and integrity, thereby fostering trust. Empirical work on digital banking, hospitality and retail supports this satisfaction-trust link in technology-mediated environments (Belanche et al. 2019, 2021; Steinhoff et al. 2019). Based on this reasoning, the following hypothesis is proposed:

Trust is the willingness to rely on a partner based on perceptions of reliability, integrity and dependability (Badrinarayanan & Ramachandran 2024; Morgan & Hunt 1994). In automotive retail, trust is particularly salient due to the high financial outlay, performance uncertainty and safety implications associated with vehicle purchase and maintenance (Brown et al. 2019; Van Tonder, Fullerton & De Beer 2020). For example, South African consumers face substantial financial exposure, as vehicle purchases often involve high capital outlays, long-term financing arrangements and ongoing servicing commitments, reflecting the scale of the domestic automotive market, which recorded nearly 600 000 new vehicle sales in 2025 (NAAMSA 2026). Trust helps customers manage perceived risk in this setting by providing confidence that a dealership will act in their best interest, deliver promised quality and provide reliable after-sales support over time.

CTT posits that trust is a central determinant of relational continuity, as customers are more likely to commit to relationships where they believe the partner is reliable and benevolent (Morgan & Hunt 1994). In digitally transforming dealership contexts, digital tools do not eliminate risk. Still, customers may reduce information asymmetry through transparent pricing, online reviews and comparison tools, potentially strengthening the role of trust in commitment formation. Empirical studies across digital banking, social commerce and omnichannel environments show that trust remains a strong predictor of commitment and relational intention, even when interactions are partially mediated by technology (Alzaidi & Agag 2022; Ozuem et al. 2024; Reydet & Carsana 2017). This suggests that system-based trust and interpersonal trust can coexist to support long-term relational commitment in hybrid journeys. Accordingly, the following hypothesis is proposed:

Satisfaction is frequently positioned as a primary determinant of behavioural intentions, including repurchase, recommendation and long-term commitment, because it signals that the relationship has generated value and is likely to do so in the future (Oliver 1980; Otto, Szymanski & Varadarajan 2020). Meta-analytic evidence indicates that satisfaction exerts a positive, though variably strong, effect on loyalty-related outcomes across industries (Otto et al. 2020). In hybrid service contexts, favourable evaluations of digital and physical touchpoints can enhance customers’ willingness to maintain relationships, as consistent satisfaction indicates reliable value delivery and reduces the perceived risk of future interactions (Pansari & Kumar 2017).

At the same time, digitalisation introduces conditions that may both weaken and strengthen the satisfaction-commitment link. On one hand, reduced switching costs and the availability of competing platforms may make customers less dependent on any single provider, potentially weakening the impact of satisfaction on commitment (Jacob, Thomas & Joseph 2024). On the other hand, when digital tools deliver high convenience, integrated experiences and time savings, customers may become more inclined to commit to providers that consistently meet their expectations, particularly in high-involvement purchases where learning and adaptation costs are non-trivial (Sumiyana & Komariyah 2024). Hence, in automotive retail, satisfaction with the integrated sales and service experience may contribute directly to customers’ willingness to maintain long-term relationships with specific dealerships. Thus, the following hypothesis is advanced:

CTT proposes that trust functions as a key mediating mechanism through which satisfaction influences long-term relational intention (Jacob et al. 2023; Morgan & Hunt 1994). Satisfied customers are more likely to perceive a firm as reliable and benevolent, which increases their willingness to commit to the relationship. In traditional dealership contexts, satisfaction has consistently been shown to increase trust, thus strengthening commitment (Mpinganjira et al. 2017; Van Vuuren et al. 2012).

Digitalisation may complicate this pathway by introducing alternative evaluative structures and potentially reducing interpersonal engagement. Nonetheless, system-based trust research indicates that digital performance cues, such as platform reliability, information accuracy and data security, can reinforce perceptions of confidence and credibility, allowing trust to operate as a mediator even when interactions are technology reliant (Belanche et al. 2021; Dai & Liu 2024). In hybrid digital-physical dealership ecosystems, satisfaction with both digital and interpersonal aspects of the journey is expected to shape commitment partly by strengthening trust.

Partial rather than full mediation is anticipated. While trust is expected to translate satisfaction into deeper relational intention, satisfaction may also exert a direct effect on commitment through habitual inertia, perceived switching costs and the convenience benefits of remaining with a familiar dealership (Otto et al. 2020). Hence, satisfaction may influence commitment directly and indirectly via trust. Hence, the following hypothesis is proposed:

Perceived service innovation reflects customers’ perceptions of the extent to which a dealership employs novel and technologically advanced processes and tools, such as digital configurators, online booking systems, automated service communication and virtual information resources, to enhance the service experience (Wan et al. 2023; Wu et al. 2024).

Service innovation may interact with the trust–commitment relationship through two competing mechanisms. Firstly, innovation may amplify the positive effect of trust on commitment (Wu et al. 2024). When customers perceive a dealership as both trustworthy and technologically progressive, innovation can serve as a signal of organisational competence, future orientation and customer centricity. These signals may strengthen customers’ confidence in the dealership’s long-term reliability and adaptive capability, thereby increasing their intention to maintain the relationship. Under this complementary mechanism, trust provides relational assurance, while perceived innovation reinforces expectations of sustained value creation, jointly strengthening commitment.

Secondly, innovation could dampen the effect of trust on commitment by providing functional assurance independent of relational confidence (Wu et al. 2024). For instance, if customers perceive that digital systems ‘just work’, booking processes are reliable, information is transparent and service reminders are seamless, they may then feel comfortable committing based on functional performance alone, even if relational trust is weaker. In this scenario, perceived service innovation partially substitutes trust as a basis for commitment, thus weakening the reliance on relational mechanisms. Given these competing possibilities, the direction of moderation is treated as an empirical question. To capture both potential patterns, the following alternative hypotheses are specified:

Perceived service innovation is conceptualised solely as a moderator, rather than as a direct antecedent for three reasons. Firstly, innovation in automotive retail primarily concerns process enhancements (e.g. booking systems and configurators), rather than changes to the core service outcome, suggesting that its primary role is contextual instead of relational. Secondly, prior literature and preliminary empirical evidence indicate that perceived innovation correlates with relational constructs but does not exhibit clear theoretical priority as an antecedent of commitment relative to satisfaction and trust. Thirdly, modelling innovation as a moderator allowed this study to address a theoretically distinct question – whether technological perceptions reshape relational processes, rather than whether innovation independently builds commitment. Figure 1 depicts the proposed research model.

This study adopted a quantitative, cross-sectional survey design to examine the relationships among CS, trust and commitment within digitally enabled automotive dealership environments. A structured online questionnaire was used to capture standardised responses from South African automotive customers.

Data were collected via a professional research agency that distributed the survey link to members of a verified national consumer panel. Before responding to the questionnaire, respondents were screened to ensure they had engaged with an automotive dealership (online or in person) within the previous 12 months. The questionnaire comprised four sections: (1) screening and consent, (2) dealership interaction behaviour, (3) demographic profile and (4) psychometric scales measuring CS, trust, commitment and perceived service innovation (see Table 2).

A pilot test with 30 respondents was conducted to assess clarity, sequencing and relevance of the items. Feedback from the pilot informed minor wording refinements, ensuring a clear and user-friendly instrument for the main data collection.

A total of 500 responses were initially obtained. After removing incomplete questionnaires and multivariate outliers identified using Mahalanobis distance (p < 0.001), 463 valid responses were retained for analysis. Respondents were South African customers aged 16 years and older who had interacted with a franchised new-vehicle dealership in Gauteng, Western Cape and KwaZulu-Natal (see Table 3).

A non-probability quota sampling strategy was employed to ensure representation across three generational groups relevant to automotive segmentation: (1) changers (< 30 years old), (2) boomers (30–49 years old) and traditionalists (≥ 50 years old). Quotas were also applied across the three provinces. Participation was voluntary and respondents completed the online questionnaire at their own convenience. The survey took approximately 10 min to complete.

All constructs were measured using multi-item Likert scales adapted from established relationship marketing and service innovation literature. Customer satisfaction, trust and commitment were measured on seven-point scales (1 = strongly disagree; 7 = strongly agree). Perceived service innovation – conceptualised as customers’ perception of a dealership’s technology-enabled service practices was also measured using seven-point Likert-type items.

Content validity was ensured through expert review by academics familiar with automotive services and by the pilot test. As covariance-based structural equation modelling (CB-SEM) requires unidimensional and psychometrically sound indicators, scale purification was undertaken during confirmatory factor analysis (CFA). Only items with satisfactory factor loadings, conceptual coherence and reliability were retained in the final measurement model. These retained items and their properties are summarised in Table 4.

Data analysis was conducted using AMOS 28 and SPSS. The two-step CB-SEM procedure was followed:

Normality was evaluated using skewness and kurtosis. To assess potential common method bias, Harman’s single-factor test was performed, and a one-factor CFA model was compared to the full measurement model. The largest single factor accounted for less than 50% of the variance, and the one-factor model showed substantially poorer fit, indicating that common method bias was unlikely to be a serious concern.

Global model fit was evaluated using χ²/df, goodness-of-fit index (GFI), adjusted goodness-of-fit index (AGFI), comparative fit index (CFI), Tucker-Lewis index (TLI), root mean square error of approximation (RMSEA) and standardised root mean square residual (SRMR). Recommended thresholds were used as benchmarks for adequate fit. The indices for the measurement and structural models are reported in Table 6.

Perceived service innovation was modelled as a moderator of the relationship between trust and commitment. A latent interaction term (trust × innovation) was specified in Analysis of Moment Structures (AMOS) using product indicators. The significance of the interaction term was assessed using bias-corrected bootstrapping with 5000 resamples. Simple slopes were examined at ±1 standard deviation of perceived service innovation to aid the interpretation of any significant moderation effects.

Ethical clearance for the study was obtained from the University of Johannesburg’s School of Consumer Intelligence and Information Systems Research Ethics Committee (Ethics Reference Number: 2024SCiiS023). Participation was voluntary, and informed digital consent was obtained from all respondents. No identifying information was collected, and all data were handled in accordance with the Protection of Personal Information Act.

Descriptive statistics and inter-construct correlations are presented in Table 7. Mean scores for satisfaction, trust and commitment were all high, indicating generally favourable evaluations of dealership relationships. Correlations between the constructs are positive and significant, thus consistent with the theorised relational mechanisms.

Confirmatory factor analysis was used to evaluate the measurement properties of the latent constructs. All standardised factor loadings were statistically significant at p < 0.001 and exceeded 0.57, with most above 0.70, indicating satisfactory indicator reliability. Cronbach’s alpha and CR values for all constructs were greater than 0.70, demonstrating internal consistency. Average variance extracted (AVE) exceeded 0.50 for each construct, supporting convergent validity. These results were reported in Table 4.

Discriminant validity was assessed using the Fornell-Larcker criterion. For each construct, the square root of its AVE exceeded its correlations with other constructs, confirming discriminant validity (Table 5). Together, these findings indicate that the measurement model demonstrates sound psychometric properties. The measurement model exhibited good fit: χ² = 431.664, df = 144, χ²/df = 2.998, GFI = 0.914, AGFI = 0.886, CFI = 0.981, TLI = 0.977, RMSEA = 0.066 and SRMR = 0.028. All indices met recommended thresholds, providing a robust foundation for structural model testing.

Following validation of the measurement model, the structural model was estimated to test the hypothesised relationships among satisfaction, trust and commitment and to incorporate the interaction term for perceived service innovation. The structural model demonstrated acceptable fit (χ² = 233.088, df = 84, χ²/df = 2.775, GFI = 0.921, AGFI = 0.887, CFI = 0.944, TLI = 0.930, RMSEA = 0.072, SRMR = 0.044). Figure 2 presents the structural model with standardised path coefficients, and Table 8 summarises the direct path estimates.

All direct hypothesised relationships were significant and positive in Table 9. Satisfaction had a strong effect on trust (β = 0.655, p < 0.001) and a significant direct effect on commitment (β = 0.415, p < 0.001), while trust also significantly influenced commitment (β = 0.356, p = 0.004).

To examine the mediating role of trust in the relationship between satisfaction and commitment, a bias-corrected bootstrapping procedure with 5000 resamples was conducted. The results are illustrated in Figure 3.

As shown in Figure 3, satisfaction has a significant positive direct effect on commitment. In addition, satisfaction exerts a significant indirect effect on commitment through trust (β = 0.050, p = 0.047). Because both the direct and indirect effects remain significant, the results indicate partial mediation.

This finding suggests that CS enhances commitment in two ways: directly and indirectly by increasing trust, which in turn strengthens commitment. Trust, therefore, operates as a relational mechanism that partially translates evaluative satisfaction into deeper dealership commitment within digitally enabled dealership relationships.

The indirect effect is statistically significant but smaller in magnitude than the direct effect, indicating that while trust plays an important explanatory role, satisfaction remains the primary driver of commitment. This supports H4.

Perceived service innovation was specified as a moderator of the trust-commitment relationship. The latent interaction term (trust × innovation) was non-significant (β = −0.009, p = 0.962), indicating that perceived innovation did not significantly strengthen or weaken the effect of trust on commitment within the tested model.

Although perceived service innovation correlated positively with satisfaction, trust and commitment at the bivariate level, its role was not conditional in the structural model. The relational pathway from satisfaction to trust and from trust to commitment appears to operate largely independently of customers’ perception of service innovation in this context.

Additional diagnostic checks confirmed the robustness of the proposed model. Variance inflation factor values for all indicators and predictors are below 2.0, indicating no multicollinearity concerns. The common method bias tests (Harman’s single-factor test and comparison of a one-factor CFA model with the full model) suggest that the data are not dominated by a single latent factor and that common method variance is unlikely to substantively bias the results.

The strong satisfaction–trust effect aligns with earlier South African research, notably Van Tonder et al. (2017), who reported similar relationships in an offline luxury dealership context. Despite significant contextual differences, including the integration of digital touchpoints, broader brand portfolios and more diverse customer demographics, the relational pattern remains consistent. This suggests that satisfaction serves as a robust anchor of relational confidence across both traditional and hybrid automotive environments. Recent empirical studies across digitally mediated service industries similarly confirm that satisfaction continues to function as a primary antecedent of trust and long-term relational outcomes even as service encounters become increasingly technology-enabled (Hollebeek et al. 2022; Rather, Hollebeek & Rasoolimanesh 2022).

The findings of this study extend prior work by conceptualising trust as a mediator rather than a parallel antecedent. While Van Tonder et al. (2017) found that satisfaction directly influenced trust and behavioural intention, the current results revealed a dual-path mechanism: satisfaction affects commitment both indirectly through trust (relational pathway) and directly through the perceived coherence of hybrid digital-physical interactions (experiential pathway). This refinement aligns with recent omnichannel research indicating that customers increasingly evaluate service encounters holistically across integrated physical and digital channels, where seamless experiences reinforce relational engagement and commitment (Becker & Jaakkola 2020; De Keyser et al. 2023).

A further distinction concerns the trust–outcome pathway. Van Tonder et al. (2017) reported no direct effect of trust on behavioural intention in a luxury setting, whereas this study found that trust significantly predicts commitment in mainstream and digitally mediated dealerships. This divergence suggests that when customers rely more heavily on digital tools and experience greater transparency across multiple touchpoints, trust may play an even stronger role in shaping relational intention. Recent relationship marketing research similarly demonstrates that trust remains a critical mechanism through which customers develop loyalty, relational commitment and long-term engagement with firms operating in digitally integrated service ecosystems (Hollebeek et al. 2022; Rather et al. 2022).

Trust partially mediates the satisfaction–commitment relationship, indicating that customers rely on both relational reassurance and holistic journey coherence when forming long-term relational intentions. The relatively stronger direct effect of satisfaction implies that hybrid experiences characterised by transparency, reliability and reduced friction can foster commitment independently of trust. This finding extends the commitment–trust theory by demonstrating that in technology-rich environments, experiential ease complements relational confidence rather than being subordinate to it. Recent research on customer engagement and digitally enabled service ecosystems similarly highlights how satisfaction, trust and engagement mechanisms interact to drive sustained customer relationships in omnichannel environments (Hollebeek et al. 2022; Rather et al. 2022).

Perceived service innovation does not moderate the trust–commitment pathway. This null effect contrasts with the literature suggesting that innovation enhances relational outcomes and therefore highlights a meaningful boundary condition. Three explanations are plausible. Firstly, customers may process functional (innovation) and relational (trust) cues through distinct cognitive systems, resulting in parallel rather than interactive effects. Secondly, trust may already operate near ceiling levels in the high-risk automotive context, leaving limited variance for innovation to amplify relational outcomes. Thirdly, innovation may function as a hygiene factor – expected by customers and appreciated when present, but insufficient to alter deeper relational mechanisms. Recent service innovation research similarly suggests that technological advancements primarily enhance service efficiency, personalisation and convenience, while relational outcomes such as commitment continue to depend on trust and consistent service quality (Becker & Jaakkola 2020; De Keyser et al. 2023; Ostrom et al. 2021).

This study contributes to relationship marketing theory in four key ways. Firstly, the results confirm the durability of CTT within hybrid digital-physical environments. Satisfaction and trust remain strong predictors of commitment, demonstrating that digitalisation complements, rather than replaces, relational mechanisms. Secondly, the identification of dual satisfaction-commitment pathways refines existing theory by showing that experiential coherence functions as an additional mechanism influencing commitment. This provides conceptual nuance to models that traditionally emphasise interpersonal interaction as the locus of relational development.

Thirdly, the non-significant moderating effect of perceived service innovation establishes an empirical boundary condition for digital transformation research. Innovation enhances functional performance but does not reshape relational dynamics in high-involvement settings. This distinction clarifies theoretical ambiguities by differentiating functional value from relational value, thereby highlighting the need for models that account for the independent – and sometimes non-overlapping – roles of technological and relational evaluations.

Fourthly, the findings contribute to emerging work on digital trust by demonstrating that customers incorporate interpersonal and system-based cues when forming trust. However, system trust does not interact with relational trust to strengthen commitment, suggesting a layered but non-interactive trust architecture. This insight emphasises the need for relationship quality models to integrate digital trust without overstating its relational influence. By contrasting the present findings with Van Tonder et al. (2017), this study expanded the applicability of relationship-quality theory in South Africa, demonstrating that relational processes in mainstream and digitally enabled dealerships are structured differently from those in offline luxury environments.

Dealership managers ought to recognise that relationship quality emerges from relational competence and the integrated performance of digital and physical touchpoints. Satisfaction influences commitment through relational and experiential pathways, requiring cross-channel quality assurance systems that ensure accurate information, pricing consistency and friction-free navigation across platforms. Trust remains central, despite digitalisation. Thus, dealerships should institutionalise organisation-wide trust-building mechanisms, transparent pricing, predictable processes, effective complaint management and consistent follow-through. Trust should be understood as a strategic organisational capability, rather than a frontline behaviour. The relational neutrality of innovation indicates that digital investments should be framed as enablers, not substitutes, for relational quality. Advanced tools cannot compensate for inconsistent service or operational unreliability. Therefore, employee training should focus on hybrid journey competence, including the ability to interpret digital traces, personalise interactions and ensure channel continuity.

Three pitfalls are particularly likely to undermine relationship quality:

By addressing these pitfalls proactively, dealerships can translate technological upgrades into sustained relational value.

Several limitations provide avenues for further research. The cross-sectional design restricts causal inference, thus longitudinal or experimental studies could clarify how satisfaction, trust and innovation perceptions evolve across repeated encounters. The reliance on self-reported measures introduces potential method bias. Hence, future studies could link perceptual data to behavioural indicators, such as service retention or CRM records.

Perceived innovation was conceptualised as a unidimensional construct, which may mask the differential impact of informational, transactional, communicative and experiential innovations. Disaggregated measures could yield more nuanced insights. Furthermore, while trust’s mediating role was confirmed, the specific psychological mechanisms through which satisfaction generates trust in digital contexts remain unexplored. Qualitative methods may illuminate these micro-level processes. Finally, future models should integrate value-based or identity-based constructs, such as perceived value or brand attachment, to assess whether relational pathways differ across mainstream and luxury segments or across generational cohorts.
