From the Chinese seller, expect these documents: 1. Vehicle registration certificate (the green book) 2. Driving license/registration card for the vehicle 3. Commercial invoice and sales contract 4. Export declaration documents (packing list, declaration forms handled by their forwarder) 5. Bill of lading, issued once the car is on the vessel You prepare on your side: 1. Import permit or approval, if your country requires one 2. Proof of compliance - emissions, safety, or type-approval certificates your customs authority asks for 3. Bill of lading release documents (original B/L or telex release) 4. Customs declaration through your broker, with your tax ID 5. Payment records - keep the bank transfer receipt, as some customs offices verify the declared value Practical tips: insist the seller removes any lien from the green book before export; verify the VIN on all documents matches the physical car; and confirm your country's age/emissions limits before paying a deposit, not after.

Such vehicles are usually cheaper but have more severe mechanical wear.

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.
