The standard process looks like this: 1. Selection: pick the car, request the VIN, registration certificate, and recent photos/videos. For higher-value cars, order an independent third-party inspection. 2. Negotiation and contract: agree on price and terms. Sign a written contract stating the car's condition, price, payment schedule, and delivery terms (FOB or CIF). 3. Deposit: typically 20-30% to reserve the car. Pay to the company's corporate account, never a personal one. 4. Verification: your agent or inspector confirms the car matches the contract before the balance is due. 5. Balance and export: pay the remaining amount; the seller arranges inland transport, export customs clearance, and port loading. 6. Shipping documents: you receive the commercial invoice, packing list, and bill of lading - usually by courier or email. 7. Arrival: your customs broker clears the car, you pay duties and taxes, then register it locally. Total timeline is usually 4-8 weeks depending on the shipping route.

Key documents to request and verify: 1. Export declaration (报关单): proves the car legally left China. Check the VIN, model and exporter name match the car. 2. Commercial invoice: must match your payment amount; customs uses it to assess duties. 3. Bill of lading: confirm the consignee is you or your agent, and the VIN/container number is correct. 4. Certificate of origin: needed for tariff preferences in some markets. 5. Condition/inspection report: ideally from an independent third party, with photos and dates. Verification tips: cross-check the VIN on every document — any mismatch causes customs holds. Ask your destination customs broker to review scanned copies before the car ships, and release the final payment only after documents pass that review. A legitimate exporter will provide all of these without hesitation.

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.
