Start by asking the seller for a photo of the full vehicle registration certificate. Check that the registered owner matches the seller's company name. Any change of ownership should appear with a transfer stamp and date. Second, request a lien check. In China, vehicle mortgages are registered with the vehicle management office. A clean certificate shows no mortgage registration; if one exists, the car cannot be legally exported until the loan is settled and the lien released. Third, verify there are no unpaid traffic fines and no gaps in compulsory insurance, since these can block export clearance. Ask the platform to include a title verification step in the transaction flow, and only pay the balance after the title transfer to the export company is confirmed.

We use two steps: 1. Insert a medical-grade endoscope through the spark plug hole to visually inspect cylinder wall scratches and carbon buildup on the piston top; 2. Extract an engine oil sample to check for large metal debris or emulsification (caused by coolant leakage).

We do not rely on the seller's verbal assurances. We provide multi-dimensional accident-free certification by cross-referencing insurance claims records, service orders from authorized dealerships, and conducting on-site paint thickness measurements and weld point inspections of the chassis and structural components (longitudinal beams, A/B/C pillars, shock absorber mounts).
