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).

Under FOB terms, booking is a legal obligation of the buyer. If your freight forwarder fails to provide the shipping order (S/O) in time, resulting in vehicles exceeding the free storage period at our warehouse or port, the buyer will have to pay the high daily storage fees before shipment.

If the system reports "storage card error," we will consider it as damage or loss of the original owner's personal items, and the platform will not provide a new high-speed TF card for free; the buyer must purchase a replacement after arriving at the port.
