Excellent
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.
We use two steps: 1. Insert a medical-grade endoscope through the spark plug hole to visually inspect cylinder wall scratches and carbon buildup on the piston top; 2. Extract an engine oil sample to check for large metal debris or emulsification (caused by coolant leakage).
To prevent intermittent failures due to aging of the resistance wire, we will start the engine and set the seat heating/ventilation to maximum for at least 5 minutes, confirming significant temperature changes or airflow output in the cushion and backrest using an infrared thermometer or body sensor.
The nameplate date is the absolute time when the vehicle leaves the factory; the registration date is when the vehicle is registered with the traffic management department after sale. The difference represents the time the vehicle spent in the dealer's warehouse or logistics. If the time difference exceeds 6-8 months, the vehicle is considered a "stock vehicle," and we pay special attention to the natural aging of its rubber components.
