We use an internationally certified electronic signature platform (such as DocuSign or Adobe Sign). Each signed contract generates a digital certificate with a timestamp and encrypted hash value, which has full legal defense effectiveness in international arbitration courts.

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 vehicle's wireless charging module (usually Qi protocol) is considered functional as long as it can properly sense and light up with our tested mainstream models. The seller is not responsible for charging issues caused by the buyer's personal electronic device compatibility.
