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.

For dealers who purchase the same brand models in bulk over a long term, we can coordinate senior technicians domestically to offer paid, regular Zoom video technical Q&A to resolve the issues you encounter locally.

Complete records represent underlying trust and zero odometer adjustment risk. In the used car market, solid data history itself carries a high premium. The extra few hundred dollars buys you an impeccable endorsement when selling overseas.
