We use a calibrated high-precision paint thickness gauge to take multiple measurements on at least 13 metal surfaces of the entire vehicle. The original paint thickness of mainstream Chinese models typically ranges from 90μm to 150μm. If any area exceeds 200μm or even reaches over 500μm, we will directly conclude that the area has undergone bodywork and filler repair.

We will never perform blind deep disassembly unless there are clear severe fault codes or extreme noises. The sealing of the engine and transmission is crucial, and compromising the factory seals to investigate non-existent issues is unprofessional. We rely on data flow and external acoustic and fluid analysis to make judgments.

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.
