Our system provides basic risk alerts based on the general regulations of the main exporting countries, but the final responsibility for confirming whether the vehicle meets the import country's regulations lies with the buyer. We will rigorously indicate the vehicle's production year, first registration date, and Chinese emission standards (such as National V, National VI) on the details page. We recommend that you submit this accurate data to the local vehicle management department or customs agent for verification before placing an order.

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.

Obtaining precise internal resistance at different SOC levels requires disassembling the battery pack and connecting it to a professional charge-discharge cabinet for several days of cycling tests. This is beyond the scope of non-destructive used car inspections; we only provide real-time estimated internal resistance data based on OBD port readings.
