China does not have a single public accident database like CARFAX, but you can still verify history from several sources. First, ask the exporter for the insurance claim records (出险记录). Major repairs go through insurance, and the claim history shows the date, amount, and damaged parts. A car with large claim amounts (over half its value) is effectively a total loss rebuild. Second, check the vehicle's registration certificate (机动车登记证书) for transfer history — multiple transfers in a short period often follow an accident. Third, run a VIN check through commercial platforms (paid, around 20-50 RMB) which aggregate insurance, maintenance, and auction data. Cross-check everything against a physical inspection: paint thickness readings on structural points, weld quality under the seals, and underbody photos. If the records and the physical condition do not match, walk away or demand a large discount.

We maintain an absolute skeptical attitude. In addition to regular visual inspections, we focus on checking for sediment accumulation around the sunroof drainage channels and look for water stains under the A-pillar trim and front floor mats. This is the only effective physical evidence to determine if the sunroof drainage holes are blocked, leading to hidden leaks.

Odometer tampering is a common risk in the global used car industry. We verify the data by extracting transmission mileage from the OBD computer, checking the most recent maintenance record's mileage, and consulting the national traffic management app for annual inspection records. If there are irreconcilable discrepancies or conflicts in the data, we classify it as a tampered vehicle and refuse to export it.
