All our measuring instruments (especially calipers, paint thickness gauges, and refrigerant pressure gauges) are calibrated quarterly according to ISO quality management system requirements to ensure the data we provide you is objective, accurate, and reliable.

Start with the paperwork: the vehicle registration certificate lists every ownership transfer, and the service book plus dealer maintenance records help confirm mileage. For digital verification, ask the seller for a live video walkaround plus a diagnostic scan report showing the ECU-recorded mileage, which is hard to manipulate. For EVs, request a battery state-of-health (SOH) report — it reveals real usage patterns far better than the odometer. Finally, a pre-shipment inspection by a third party should include structural checks (pillars, chassis rails) to rule out accident repairs. Build "no major accident, no flood or fire damage" into your purchase contract with a refund clause if the inspection contradicts it.

Please take timestamped photos and videos at the first opportunity when picking up the car at the destination port (before leaving the port area). We will compare these with the final archived images taken at the Chinese port before shipping. If it is confirmed that we missed reporting it during the pre-shipment inspection, we will provide compensation for parts or labor costs based on the severity of the defect; if it is new physical damage incurred during shipping, the insurance claim process will need to be initiated.
