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).

Based on practical risk assessment, we strongly recommend setting aside 3% to 5% of the car price as a buffer fund for even the highest-rated used cars, to cover oil changes, new tires, minor shipping scratches, and local inspection labor costs.

We understand that the power battery is the core asset of an EV. Before export, our technical team will use professional OBD diagnostic equipment to read the underlying data from the Battery Management System (BMS). We will provide you with a technical report that includes key indicators such as battery health percentage (SOH), cell pressure differences, and charge-discharge cycle counts. If the SOH is below our established export safety standard (usually above 80%, depending on the vehicle's age), the vehicle will be intercepted and not sent overseas.
