Thank you for your interest in Beijing Catech Zhongchi Preferred Selection, specializing in high-quality used cars. We hope every car you buy is one you love! ① All vehicles in our store have passed third-party professional inspections, guaranteeing no major accidents, no water damage, no fire damage, and accurate mileage. ② All vehicles in our store come with a 30-day full vehicle warranty and a one-year or 30,000-kilometer warranty on the three major components (engine, transmission, and chassis). Buy with confidence and use with peace of mind.
If the car has been maintained at an authorized dealer, we can extract the desensitized official maintenance history (including entry time, mileage, and maintenance items) through a paid third-party data provider and provide it to you. If some year records are missing, we will honestly inform you that the "records are incomplete."
We maintain an absolute skeptical attitude. In addition to regular visual inspections, we focus on checking for sediment accumulation around the sunroof drainage channels and look for water stains under the A-pillar trim and front floor mats. This is the only effective physical evidence to determine if the sunroof drainage holes are blocked, leading to hidden leaks.
Obtaining precise internal resistance at different SOC levels requires disassembling the battery pack and connecting it to a professional charge-discharge cabinet for several days of cycling tests. This is beyond the scope of non-destructive used car inspections; we only provide real-time estimated internal resistance data based on OBD port readings.
