We will directly check the registration certificate (the big green book) and count the number of changes.

4S dealership records are directly connected to the manufacturer's database, making the data hard to tamper with and the most reliable, with original parts guaranteed; third-party repair shops usually are not connected, making their data unverifiable. Therefore, we only consider the connected records from 4S dealerships as valid historical documentation.

A clean title check has three layers. First, run the VIN through maintenance records: dealers in China log service visits with mileage, and gaps or mileage rollbacks are red flags. Second, pull insurance claim history — major accidents, fire and flood damage usually leave claim records even if the car was repaired well. Third, verify registration status: confirm the car is not under finance, court seizure, or theft report. From overseas, you can engage a local inspection agency or law firm to retrieve these records and issue a written report. Cross-check the VIN and engine number on the report against the registration certificate; any mismatch means walk away.
