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).

It depends on the situation. If the video inspection reveals significant mechanical faults or structural damage not disclosed in the inspection report, the deposit will be refunded 100% unconditionally; however, if the buyer defaults for subjective reasons (such as suddenly not liking the color or financial issues), the deposit will be retained as compensation for taking the vehicle off the market.

Rules differ by country. Many markets limit the age of imported used cars (commonly 3-5 years), require left-hand drive, and set minimum emission standards such as Euro 4, 5 or 6. Some regions additionally require a local conformity certificate before the car arrives. Practical steps before any deposit: check your customs authority's official website, or spend 20 minutes with a local customs broker who imports vehicles regularly; give the exporter your country's requirements and the VIN, and ask for proof of the car's emission level (China's standards map roughly to Euro equivalents); confirm the exact model was legally exportable from China. A short verification call at the start can prevent the car being refused entry — or impounded — months later.
