Start with the paperwork: the vehicle registration certificate lists every ownership transfer, and the service book plus dealer maintenance records help confirm mileage. For digital verification, ask the seller for a live video walkaround plus a diagnostic scan report showing the ECU-recorded mileage, which is hard to manipulate. For EVs, request a battery state-of-health (SOH) report — it reveals real usage patterns far better than the odometer. Finally, a pre-shipment inspection by a third party should include structural checks (pillars, chassis rails) to rule out accident repairs. Build "no major accident, no flood or fire damage" into your purchase contract with a refund clause if the inspection contradicts it.

Heavy-use vehicles often look clean in photos but show specific wear patterns. Here's what to check: 1. Rear sag and suspension: ask for a side-profile photo of the car on level ground. If the rear sits noticeably lower than the front, the rear springs or shocks may be worn from constant heavy loads. Compare with factory ride height specs. 2. Pedal and seat wear: accelerator and brake pedals with polished metal patches, and a driver's seat bolster that is flattened or cracked, indicate high mileage or intensive commercial use — even if the odometer says otherwise. 3. Hitch and tow bar marks: check the rear bumper area in close-up photos for scratches, bolt holes, or a removed tow bar mount. Ask the seller directly whether the car ever towed. 4. Underbody and frame: request underbody photos. Look for bent or scraped crossmembers, fresh undercoating hiding damage, or uneven tire wear across the rear axle. 5. Data check: many ride-hailing cars in China have records in maintenance databases — a professional inspection agency can flag cars with commercial fleet history. If the seller refuses underbody or close-up photos, treat it as a warning sign and consider another vehicle.

Act fast and follow the paper trail you built before buying. First, document everything immediately: take photos and videos of the fault, note the date of arrival and the odometer reading. Most exporters offer a commercial warranty window (typically 15-30 days after arrival) for major components like the engine, transmission and high-voltage battery. Contact the exporter in writing with the evidence, referencing your contract's warranty clause. For minor issues, a common arrangement is that they air-freight the spare part to you or reimburse a capped repair amount at a local workshop. To protect yourself before purchase: get the warranty terms written into the sales contract, including response time, what is covered, and how parts compensation is calculated. Also ask which fast-wearing parts (brake pads, filters, wipers) they recommend buying together with the car, so you are not stuck waiting for a small part from overseas.
