We use an internationally certified electronic signature platform (such as DocuSign or Adobe Sign). Each signed contract generates a digital certificate with a timestamp and encrypted hash value, which has full legal defense effectiveness in international arbitration courts.

Do not use a high-pressure water gun directly! The high-pressure water can instantly damage the fragile aluminum fins of the condenser, leading to a permanent decrease in cooling efficiency. We can only use a low-pressure air gun or a soft brush for surface cleaning.

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.
