Remote mechanical assessment relies on documented evidence: 1. Cold-start video: Ask for a video of the engine starting from cold — listen for rattles, watch for smoke (blue = oil burning, white = possible head gasket issue). 2. OBD scan: A full diagnostic scan reveals fault codes in the engine, gearbox, and electronics. Request the raw scan report, not a screenshot summary. 3. Service records: Cross-check mileage against maintenance records and inspection stickers; consistent records indicate a cared-for car. 4. Fluid check: Photos of the oil dipstick and coolant color tell a lot — milky oil or rusty coolant are red flags. 5. Test drive video: A short drive video shows gear shifts, braking, and steering behavior. Combine these with the pre-shipment inspection report. A seller who refuses to provide cold-start video or OBD data is a warning sign.

Before shipping you should hold: the sales contract and commercial invoice, the export declaration (customs form showing the VIN), the vehicle registration certificate, and the bill of lading or rail waybill once cargo is loaded. Verify them like this. The VIN on the invoice, the export declaration, and the waybill must be identical, character for character. The registration certificate should show a clear ownership chain with the seller as the current owner; ask for a scan before payment. The export declaration proves the car legally left China and is essential for customs clearance at destination. If the exporter cannot provide the registration certificate or hesitates on the VIN check, pause the deal. Also confirm who handles the document courier: originals should arrive before or with the vessel, because many ports will not release a car without original bills of lading.

Air suspension is very delicate. If, after the vehicle has been stationary for about 12 hours, the height on one side of the vehicle drops more than 1.5 cm when measured from the wheel arch to the tire, we will determine that there is a slight air leak in the air spring or distribution valve on that side and warn you of the high subsequent repair costs.
