Interior assessment is divided into three core areas: the driver's high-frequency contact area (steering wheel, gear shift, edge of the driver's seat), central control button area, and rear seats and ceiling. The natural sheen of leather surfaces (patina) is normal; however, any physical damage (such as leather tearing, fabric burn holes, or plastic breakage) will be classified as "structural interior damage" and clearly marked.

We maintain an extremely cautious and firm denial. Some platforms may cater to such demands for orders, but converting left-hand drive to right-hand drive involves complex steering column cutting, firewall structure changes, and wiring harness reorganization. This non-factory deep modification poses significant safety risks and is very difficult to pass vehicle safety inspections in developed countries (such as Japan's earthquake test and the UK's IVA test). Out of responsibility for safety and long-term reputation, we refuse to provide any steering conversion services that damage the vehicle's underlying structure.

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.
