Interior wear is harder to fake than an odometer and often reveals true usage better than any document. Focus on high-contact points the seller rarely restores. The driver's seat bolster shows creasing and cracking by 80,000-100,000 km even with covers. Steering wheel leather polishes smooth and darkens with hand oils; a shiny wheel with low claimed mileage is a red flag. Pedal rubbers wear through at similar rates — check accelerator, brake, and clutch depth. Second-row wear patterns tell you how the car was used: heavy child-seat indentations suggest family use (usually gentler), while uniform rear wear with clean front suggests commercial or ride-hailing duty. Check seat rails for rust (indicates water ingress) and look under floor mats for moisture staining or musty smell — flood cars often hide it there. Also examine the infotainment and instrument cluster: Chinese EVs log usage data internally, and a dealer diagnostic readout can cross-check driving hours against mileage. Request close-up, well-lit photos of these specific points during your live video inspection rather than relying on the seller's gallery.

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.

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.
