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.

It's extremely difficult. Unauthorized modifications can lead to module current overload protection, resulting in a lock. In China, you need to use the factory online engineer account to reprogram it. It's basically impossible to perform online decoding overseas. We strongly warn against blindly modifying the electrical systems of modern integrated circuit vehicles.

1) Verify the company: business license, export track record, and a live video call where they show the actual car and its VIN. 2) Hire an independent pre-shipment inspection. 3) Sign a contract stating the VIN, specs, price, Incoterm, and refund conditions. 4) Pay a 20–30% deposit by bank transfer only after the contract is signed — never the full amount, and never to a personal account. 5) After the inspection passes, pay the balance against a copy of the bill of lading. 6) Track the shipment and prepare import documents. 7) Inspect the car on arrival before releasing any final documents. Each step is a checkpoint. Don't let the seller rush you past one.
