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.

Absolutely not. The aging and cracking of rubber parts are inevitable over time and are a normal manifestation of vehicle depreciation. Our compensation only covers sudden and catastrophic mechanical failures, such as engine cylinder scoring or transmission gear breakage.

Because it's not a one-time transaction. Only by ensuring compliance checks, improving after-sales service, and providing parts can a good reputation be established, leading to repeat purchases and long-term cooperation.
