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.

Odors are difficult to convey through images, so our quality inspectors conduct subjective smell assessments and record them. For vehicles with severe smoke or mold odors, if deep ozone sterilization is ineffective, we will downgrade the vehicle and mark the report with a red "Odor Warning" at the top.

This is a key legal issue. If the inspection is conducted by a third party appointed by us, we will be the primary responsible party and provide limited compensation to you, after which we will seek reimbursement from the inspection agency; if the inspection agency is designated by you personally (such as SGS), you will need to file a claim directly with that agency according to its service terms.
