RoRo (roll-on/roll-off): the cheapest per car for running vehicles. Cars are driven onto the vessel and secured on decks. Transit to major ports (Jebel Ali, Rotterdam, Karachi) takes 15 to 35 days. Downside: cars are exposed to weather and salt air, and minor handling scratches happen occasionally. Container (20ft/40ft): one 40ft high-cube fits one car with parts, or two small cars with racking. Cost is higher than RoRo but cars are sealed and protected. Best for high-value vehicles, EVs (battery safety rules often require container), or when shipping spare parts together. Flat rack: for oversized vehicles (trucks, buses, modified cars). Priced per dimensions. Practical advice: for a standard used car to a port with RoRo service, choose RoRo and add marine insurance (0.3%–0.8% of value). If your destination lacks RoRo calls or you ship an EV, use a container. Always get the booking confirmation and bill of lading copy before paying the final balance.

Odometer fraud exists everywhere, but cross-checking several data points makes it hard to fake: 1) Maintenance records: ask for service history with mileage entries. Gaps or resets are red flags. 2) Tire wear: a car showing 30,000 km should not have nearly bald tires. Compare tread depth against the claimed mileage. 3) Pedals, steering wheel, and seat bolsters: heavy wear on these with low odometer readings is a classic mismatch. 4) Diagnostic scan: request an OBD readout. Many control modules store mileage data internally — if the ECU shows 120,000 km while the dash shows 40,000, you have your answer. 5) Vehicle history report: in China, apps and platforms can pull insurance claim records and registration history, which often reveal the true mileage trail. Always request a live video showing the odometer with the engine running, and have the number written into your contract.

China does not have a single public accident database like CARFAX, but you can still verify history from several sources. First, ask the exporter for the insurance claim records (出险记录). Major repairs go through insurance, and the claim history shows the date, amount, and damaged parts. A car with large claim amounts (over half its value) is effectively a total loss rebuild. Second, check the vehicle's registration certificate (机动车登记证书) for transfer history — multiple transfers in a short period often follow an accident. Third, run a VIN check through commercial platforms (paid, around 20-50 RMB) which aggregate insurance, maintenance, and auction data. Cross-check everything against a physical inspection: paint thickness readings on structural points, weld quality under the seals, and underbody photos. If the records and the physical condition do not match, walk away or demand a large discount.
