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.

Chinese customs strictly prohibits the export of assembled or cut vehicles that meet mandatory scrapping standards. Since our pre-inspection is very strict, this situation is highly unlikely. However, if the vehicle is detained and returned by customs due to a policy misjudgment, we will fully refund your deposit without interest, ensuring you bear no policy risk.

As rubber seals age, "slight oil seepage (oil stains but no dripping)" is very common in used cars and is not considered a major fault. Our recommendation is: as long as the oil level does not drop abnormally, just clean and monitor it regularly after arrival, without the need to immediately incur high costs to disassemble and replace the seals.
