We maintain an absolute skeptical attitude. In addition to regular visual inspections, we focus on checking for sediment accumulation around the sunroof drainage channels and look for water stains under the A-pillar trim and front floor mats. This is the only effective physical evidence to determine if the sunroof drainage holes are blocked, leading to hidden leaks.

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.

It rarely happens, but there is a clear mechanism. If the transaction is canceled due to our reasons (such as the vehicle being suddenly seized by judicial authorities during the transfer), we will refund the full deposit you have paid and provide additional compensation according to the penalty clauses in the contract.
