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.

The platform has strict internal outbound inspections. If buyers need, we can assist you in commissioning an independent third-party evaluation agency (such as Cha Doctor, Dongche Di official testing, etc.) for re-inspection, with costs borne by the buyer. An independent report can provide more credibility for your local resale.

Test-drive cars experience much more mechanical wear due to extreme conditions like cold starts and emergency braking compared to regular family cars. We can identify this by tracing whether the first owner was a 4S dealership or the manufacturer. If so, we will reassess its value based on "operational intensity" standards.
