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.

VIN consistency is checked at customs in both China and your country, and a mismatch can block clearance. Do the following: 1. Verify early: before payment, ask for clear photos of the VIN plate (dashboard, door frame, engine bay on some models) and compare them with the VIN on the purchase contract, inspection report and any registration documents. 2. Check the characters: VINs never contain the letters I, O or Q. If you see them, the document is either fake or mistyped. 3. Decode it: the first 3 characters are the world manufacturer code, characters 4-8 describe the model and configuration. Decode it online to confirm the documents match the actual trim level you are buying. 4. At destination: when the car arrives, re-check the VIN against the bill of lading and your import declaration before accepting delivery. Any discrepancy found before shipping can be corrected cheaply; after arrival it becomes a legal problem. Make VIN verification part of your pre-shipment inspection checklist.

Odometer rollback happens everywhere, so never trust the dashboard number alone. Cross-check at least three sources: 1. Maintenance records: Chinese 4S dealerships keep service logs tied to the VIN. Ask the exporter for screenshots showing recorded mileage at each visit — the numbers should rise consistently. 2. Inspection reports: China requires periodic emissions/safety inspections, and the mileage is logged at each one. The exporter can pull the car's inspection history. 3. Tire and wear clues: Compare the claimed mileage with brake pedal rubber, steering wheel shine, seat bolster wear, and the tire production dates. A car showing 30,000 km with a polished steering wheel and second set of tires is suspicious. Also check the dashboard for uneven digits or scratches around the odometer area in photos. If maintenance and inspection records roughly agree, the reading is usually trustworthy; if the seller refuses to share records, treat the mileage as unknown and negotiate accordingly.
