We thoroughly rule them out by checking if the cabin wiring harness is melted, if the seat belts have water stains or mold, if there is unusual rust or debris in the seat tracks and cigarette lighter, and by verifying with the insurance company for any "total loss claims." These two types of cars are an absolute sales ban for us.

China has centralized vehicle records you can check remotely before paying anything. Ask the exporter for the 17-digit VIN, then request two reports. First, the maintenance history: third-party platforms pull 4S dealership records showing service dates, mileage and repair items. A mileage line that goes down over time is a red flag for odometer tampering. Second, the insurance claim history: it lists accident dates, claim amounts and repaired parts. Heavy claims involving frame rails or airbags should end the deal. Practical tips: run the reports yourself instead of accepting screenshots from the seller, make sure the report date is close to the delivery date, and cross-check with physical wear such as the steering wheel, pedals and seat bolsters, which cannot lie about high mileage. Keep in mind that small private repairs never enter these databases, so combine history checks with a physical inspection before shipping.
