I. Case Background: From Initial Cooperation in 2022 to Contract Renewal and Expansion in 2024. In 2022, the Urban Management Bureau of a certain district launched its first public tender to procure a batch of Foton Fengjing service vehicles, aiming to enhance street environmental maintenance efficiency within its jurisdiction. These vehicles are primarily used for daily inspections, equipment transportation, and emergency response tasks. Following a rigorous tender evaluation process, Chengli Special Purpose Vehicle Co., Ltd. (hereinafter referred to as “Chengli”) secured the contract and successfully delivered the first batch of five Foton Fengjing service vehicles, leveraging its advantages of factory-direct sales, comprehensive after-sales commitments, and extensive experience in government procurement. According to publicly available tender information, the unit price of these vehicles was approximately RMB 120,000, with a total contract value of around RMB 600,000. The vehicle configuration strictly complies with China VI emission standards; the chassis is sourced from Foton, while the superstructure is custom-modified by Chengli according to the actual operational requirements of the Urban Management Bureau—including compartmentalized cargo boxes, installation of warning lights, and optimized storage cabinet layout. During the two-year operational period following deployment, these vehicles demonstrated stable performance without any major failures, and their routine maintenance costs remained lower than those of comparable models. In 2024, the Urban Management Bureau initiated another procurement project, deciding to renew the contract and expand the fleet by adding three more units of the same Foton Fengjing service vehicle model, with the total budget capped at approximately RMB 399,000. This renewal not only reflects the client’s strong confidence in Chengli’s products and services but also serves as a practical, referenceable procurement case for other municipal authorities. II. User Feedback: Why Did the Client Choose to Renew the Contract? During the 2022–2024 usage cycle, the fleet manager of the Urban Management Bureau provided the following key feedback points: • High Vehicle Reliability: The Foton chassis itself offers excellent reliability, and Chengli’s strict adherence to official announcement parameters (e.g., manufacturing standards for models such as CLW5070GSSD6) during modification ensures smooth and stable operation under diverse road conditions. • Prompt After-Sales Response: Chengli guarantees “nationwide warranty coverage for Dongfeng chassis and lifetime service support for Chengli-fitted superstructures.” In practice, when minor issues arise, Chengli’s after-sales team delivers spare parts or technical support within 24 hours—significantly minimizing vehicle downtime. • Outstanding Cost Control: Compared to purchasing through authorized 4S dealerships, Chengli’s factory-direct model enables savings of approximately RMB 8,000–15,000 per unit for identical configurations. This translated into over RMB 40,000 in cost savings for the initial batch of five vehicles—funds subsequently reallocated to maintenance of other sanitation equipment. • Complete Official Announcements, Hassle-Free Registration: All vehicles carry complete official announcements and were smoothly registered, inspected annually, and licensed for commercial operation in Xiangyang, encountering no regulatory or administrative obstacles. “After two years of use, these vehicles have required virtually no repairs beyond routine maintenance. Chengli’s after-sales hotline () is always accessible, and spare parts arrive quickly. So, for this renewal, we didn’t hesitate—we chose Chengli again.” — Fleet Manager, Urban Management Bureau (paraphrased based on client feedback) III.
