The intensifying competition among used-car showrooms requires optimal vehicle quality management and customer service to build consumer trust. Jati Subur Mobil Showroom in Surabaya still faces challenges in maintaining consistent vehicle care and customer service amid this competitive business environment. This community service activity aims to assist the partner in implementing product maintenance management strategies to improve vehicle management and customer service quality. The method applied consultation, education, and direct mentoring through the stages of observation, problem identification, strategy implementation, monitoring, and evaluation, with data analyzed descriptively. The activity was conducted from February to May 2026 through education on routine vehicle inspection, quality control, cleanliness management, and strengthened service communication. The results show that vehicle management became more structured and consistent, while service quality improved through responsive, informative, and transparent communication with consumers. The activity is concluded to have strengthened consumer trust and the sustainable competitiveness of the used-car showroom.
