To ensure the legal rights of both parties, the "International Used Car Sales Contract" we signed is in both Chinese and English. Generally, the contract is governed by Chinese law. All liabilities for breach of contract and force majeure clauses will be clearly defined in the contract.

Battery condition is the single most important — and most expensive — variable in a used EV. Ask for a State of Health (SOH) report: in China, dealers and authorized service centers can read it via the manufacturer diagnostic system. It shows remaining capacity as a percentage of the original. Rule of thumb: above 90% is excellent, 85-90% is acceptable for the price, below 80% needs a serious price cut or battery refurbishment. Also get the battery's full charge and discharge history (次数) — a 3-year-old car with 800 fast-charge cycles has lived a harder life than one with 200. Physically, inspect the battery pack enclosure on a lift for dents, corrosion, or coolant leaks. Check that DC fast charging works during a test charge. Finally, verify the battery is not covered by an open recall or replacement program — this is both a risk and sometimes a free upgrade.

The standard set: commercial invoice, packing list, bill of lading, export customs declaration, certificate of origin, and a copy of the vehicle title/registration. How to verify: the bill of lading number should be trackable on the shipping line's website; the certificate of origin is verifiable through CCPIT's online system; and the VIN must match across all documents, the inspection report, and the car itself. Ask for scans of everything before paying the balance, and have a freight forwarder review the set. Mismatched VINs, missing title copies, or vague promises that "documents will follow" are red flags worth pausing the deal over.
