Test-drive cars experience much more mechanical wear due to extreme conditions like cold starts and emergency braking compared to regular family cars. We can identify this by tracing whether the first owner was a 4S dealership or the manufacturer. If so, we will reassess its value based on "operational intensity" standards.

The commercial invoice and export license we provide are based on the vehicle's underlying VIN and official Chinese nameplate data. If there are minor discrepancies with the destination country's customs system parameters (such as curb weight), we will issue a "Parameter Explanation Letter" stamped by our company to assist you in explaining, but we cannot change the official document data.

We will use a megohmmeter (insulation resistance tester) to measure the insulation resistance of the high-voltage bus. If the resistance value is below the national safety standard, it indicates a risk of leakage, and the vehicle will be deemed unqualified.
