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).

FOB (Free On Board): Includes the purchase price of the vehicle, transfer fees for registration in China, export license fees, logistics costs for trucking to the port within China, and port handling and customs fees. CIF (Cost, Insurance, and Freight): In addition to FOB, it includes the shipping cost from China to your designated destination port (RoRo or container), as well as cargo insurance during international shipping.

We use an internationally certified electronic signature platform (such as DocuSign or Adobe Sign). Each signed contract generates a digital certificate with a timestamp and encrypted hash value, which has full legal defense effectiveness in international arbitration courts.
