Due to legal restrictions preventing unregistered vehicles from high-speed driving on public roads in China, most of our dynamic tests are conducted in a closed area (with a maximum speed of around 60 km/h). This is sufficient to test for suspension noise and low gear smoothness, but it cannot simulate high-speed wind noise and tire balance vibrations at 120 km/h.

The core background report we provide (including basic information, mileage verification, and accident investigation conclusions) supports both Chinese and English outputs to ensure that overseas buyers or your end customers can read it without barriers.

A proper third-party inspection has four parts, and you should insist on all of them. 1. Lift inspection: the car goes on a hoist to examine the underbody, frame rails, suspension arms and oil pan for impact damage or leaks — areas no photo set can cover. 2. Paint thickness check: a gauge reading from every panel. Inconsistent or very high values reveal repainting; structural points like the A/B/C pillars matter most because they indicate accident repairs. 3. OBD diagnostics: fault codes and live data from the engine, transmission, ABS and airbag modules. Stored historical codes often tell the truth the dashboard hides. 4. Road test: cold and warm driving to check shifting, braking and unusual noises. The report should carry the VIN, inspection date and the agency's stamp or digital signature. It costs very little compared to the price of the car, and it filters out most problem vehicles before your money moves.
