4S dealership records are directly connected to the manufacturer's database, making the data hard to tamper with and the most reliable, with original parts guaranteed; third-party repair shops usually are not connected, making their data unverifiable. Therefore, we only consider the connected records from 4S dealerships as valid historical documentation.

Chinese customs strictly prohibits the export of assembled or cut vehicles that meet mandatory scrapping standards. Since our pre-inspection is very strict, this situation is highly unlikely. However, if the vehicle is detained and returned by customs due to a policy misjudgment, we will fully refund your deposit without interest, ensuring you bear no policy risk.

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).
