A proper third-party inspection has four parts, and you should insist on all of them. 1. Lift inspection: the car goes on a hoist to examine the underbody, frame rails, suspension arms and oil pan for impact damage or leaks — areas no photo set can cover. 2. Paint thickness check: a gauge reading from every panel. Inconsistent or very high values reveal repainting; structural points like the A/B/C pillars matter most because they indicate accident repairs. 3. OBD diagnostics: fault codes and live data from the engine, transmission, ABS and airbag modules. Stored historical codes often tell the truth the dashboard hides. 4. Road test: cold and warm driving to check shifting, braking and unusual noises. The report should carry the VIN, inspection date and the agency's stamp or digital signature. It costs very little compared to the price of the car, and it filters out most problem vehicles before your money moves.

Mainstream Chinese automakers rarely publish official English versions of their underlying circuit diagrams. We can provide some models' original Chinese technical documents (PDF) for B2B clients, which you will need to translate for your local mechanics using translation software.

The key document is the 机动车登记证书 (Vehicle Registration Certificate), the green booklet proving ownership. Along with it, the seller should provide the 行驶证 (driving license for the vehicle) and their ID. Verification steps: 1. Check that the VIN/chassis number on the certificate matches the car exactly, stamped on the dashboard and door frame 2. The certificate's 所有人 (owner) field must match the seller's company name or the export agent they claim to work with 3. Look at the registration history pages—frequent transfers in a short period can indicate problem cars being flipped 4. Confirm the car is not marked 抵押 (mortgaged/pledged to a bank) Be cautious if the seller only shows photos of these documents and refuses a live video panning across the original booklet with the day's newspaper. Also verify the export company has 二手车出口资质 (used-car export qualification)—a legitimate exporter will share their license number, which you can cross-check on Chinese commerce bureau websites.
