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.

4S dealership records are directly connected to the manufacturer's database, making the data hard to tamper with and the most reliable, with original parts guaranteed; third-party repair shops usually are not connected, making their data unverifiable. Therefore, we only consider the connected records from 4S dealerships as valid historical documentation.

1) Verify the company: business license, export track record, and a live video call where they show the actual car and its VIN. 2) Hire an independent pre-shipment inspection. 3) Sign a contract stating the VIN, specs, price, Incoterm, and refund conditions. 4) Pay a 20–30% deposit by bank transfer only after the contract is signed — never the full amount, and never to a personal account. 5) After the inspection passes, pay the balance against a copy of the bill of lading. 6) Track the shipment and prepare import documents. 7) Inspect the car on arrival before releasing any final documents. Each step is a checkpoint. Don't let the seller rush you past one.
