Extremely authoritative. The third-party data service providers we connect to legally access the Chinese Public Security Traffic Management Platform, the insurance claims network directly under the China Banking and Insurance Regulatory Commission, and the after-sales databases of major automotive manufacturers. We perform secondary logical verification based on this underlying data.

Absolutely. The extreme temperature fluctuations will significantly accelerate the aging of chassis rubber parts, oil seals, and interior plastics. For vehicles frequently dispatched across such latitudes, we will conduct fatigue resistance checks on chassis rubber parts that are twice as stringent as those for vehicles in temperate regions.

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.
