A typical payment structure looks like this: 1. Deposit: 10-30% after you confirm the car and price, often to reserve the vehicle and start the inspection. 2. Balance: paid after you approve the inspection report, but before or at shipment. A common safeguard is paying against a copy of the bill of lading, with telex release of the original B/L after funds arrive. 3. Never send 100% upfront to a new supplier. Use traceable methods (T/T bank transfer to a corporate account matching the company name, or escrow for first orders) and keep every agreement in writing. 4. Timeline: quote within days, inspection 3-7 days, booking and loading 1-2 weeks, ocean transit 3-6 weeks, customs clearance 3-10 days. Red flags: personal bank accounts, pressure to skip inspection, prices far below market.

Experience turbo lag and power surge during road tests; check for significant oil accumulation at the turbo intake and intercooler connections (slight oil vapor is normal); and use OBD to read the real-time boost pressure peak to see if it meets factory settings.

In practice, returning an imported car is extremely difficult, so your protection must be built in before payment, not after. Once a used car has been exported, reversing the transaction involves re-export paperwork, duties, and freight costs that typically exceed any refund you'd recover. Most exporters' contracts treat the sale as final once the bill of lading is issued. What you can realistically do: 1. If the car differs materially from the contract (wrong VIN, undisclosed accident, tampered odometer), you have grounds for a claim. Document everything and negotiate a partial refund or repair credit—full refunds are rare. 2. If the seller committed outright fraud, you can pursue legal action in China or report to the platform, but cross-border enforcement is slow and costly. 3. Some exporters offer a short arrival warranty (usually 30-90 days) covering major mechanical failures. Claims require immediate notification, third-party inspection reports, and proof the damage existed at shipment. The practical takeaway: never rely on the possibility of a return. Spend the money on a thorough pre-shipment inspection and clear contract terms instead—it's far cheaper than a dispute.
