We use quantitative standards. Minor scratches less than 3 cm that do not reach the base coat (which can be polished) are considered normal wear; scratches over 3 cm deep to the base coat or dents larger than 2 cm in diameter will be highlighted in the inspection report's "Appearance Defect Distribution Map" with close-up photos.

All vehicles on the lift must be inspected. We will provide high-definition close-up photos of the chassis directly below, suspension components, and the mid to rear section of the exhaust. We will honestly show any minor surface rust (a common phenomenon in cast iron); if we find bent longitudinal beams or extensive through-corrosion, the vehicle will be scrapped and not exported.

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.
