Due to legal restrictions preventing unregistered vehicles from high-speed driving on public roads in China, most of our dynamic tests are conducted in a closed area (with a maximum speed of around 60 km/h). This is sufficient to test for suspension noise and low gear smoothness, but it cannot simulate high-speed wind noise and tire balance vibrations at 120 km/h.

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 directly check the registration certificate (the big green book) and count the number of changes.
