This study aims to explore the key factors influencing consumer adoption of used electric vehicles (UEVs), an area that remains under-researched despite its growing relevance in sustainable mobility. Integrating the Theory of Planned Behavior (TPB) and the Technology Acceptance Model (TAM), the research employs a qualitative thematic analysis based on the expert interviews to examine constructs such as attitude, subjective norm, perceived behavioral control, perceived usefulness, and perceived ease of use. The analysis reveals that, beyond these established constructs, UEV-specific concerns such as battery reliability, information asymmetry, and residual values influence consumer risk perception. In addition, psychological dimensions like environmental self-identity and trust in institutions are found to mediate behavioral intentions. Compared to new electric vehicles, UEV adoption involves more complex decision-making, with consumers factoring in retrospective evaluations, technological uncertainties, and secondary market dynamics. This study contributes novel insights by extending traditional behavioral models to include post-use transparency, lifecycle information, and ecosystem readiness. The findings offer practical implications for industry stakeholders and policymakers, highlighting the need for transparent pricing, standardized battery diagnostics, and reliable certification systems. Ultimately, this research enhances the understanding of behavioral mechanisms in the UEV market and supports the advancement of more inclusive and sustainable electric mobility solutions.
