It rarely happens, but there is a clear mechanism. If the transaction is canceled due to our reasons (such as the vehicle being suddenly seized by judicial authorities during the transfer), we will refund the full deposit you have paid and provide additional compensation according to the penalty clauses in the contract.

A Chinese history report (查博士, 精真估, or 4S-shop records) usually contains several sections. Here's how to read them. Accident records: entries tagged 重大事故 (major accident) or listings at an insurance payout above 30% of the car's value are serious red flags. Airbag deployment is a deal-breaker for most buyers. Mileage timeline: check that mileage increases logically between service visits. A sudden drop between two dates means odometer tampering—walk away. Ownership count: more than 3 owners in 5 years suggests a problem car. Also check the 使用性质 field: a car registered as 营运 (commercial/taxi use) has a much shorter legal lifespan. Maintenance entries: consistent 4S dealership records are a good sign; long gaps aren't necessarily fatal if the owner used independent shops, but ask for receipts. Cross-check the report against the VIN plate, registration certificate, and physical inspection. If the report shows no accidents but paint thickness readings say otherwise, trust the metal, not the paper.

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.
