Once the car system (especially in a closed ecosystem) undergoes a major version upgrade, its bootloader is usually locked, preventing downgrades. If this happens, there is basically no solution in an overseas environment. Therefore, we strongly warn: do not blindly insert a USB drive to upgrade while offline.

Absolutely not. The U.S. DOT and EPA have strict import restrictions on non-compliant vehicles. Any Chinese used car that is not 25 years old and not produced to U.S. standards will face mandatory crushing and destruction upon arrival at U.S. ports. We directly reject such non-compliant orders.

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.
