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.

You can watch the car through live streaming or VR, or entrust a local third-party agency to inspect the car for you. Transparency about the car's condition is the foundation of trust.
