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 will carefully check if the chassis number on the windshield, chassis, and door frame matches.

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.
