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).

China's vehicle data is less centralized than in the US or Europe, but you can still verify a lot: 1. Ask the exporter for the VIN and order a third-party history report from Chinese services; they aggregate insurance claims and repair records. 2. Cross-check the registration date on the title with the odometer—a 3-year-old car showing 30,000 km but registered as a ride-hailing vehicle is a red flag. 3. Request maintenance records from the brand's dealer network; digital records are increasingly common. 4. Verify the seller legally owns the car: the registration certificate name should match the exporter's business license. Gaps are common, so treat the history report as one input, not proof. Combine it with an independent pre-purchase inspection, and hold back part of the payment until the inspection passes.

Our foreign versions of the report standardize terminology and include illustrations. For example, instead of just writing "control arm failure," we specify "Lower Control Arm Bushing Torn" to help your local technicians identify the issue directly.
