Two separate protections matter: cargo insurance and contractual risk transfer. Cargo insurance: for container or RoRo shipments, buy marine cargo insurance covering total loss and damage, typically 110% of the CIF value (average cost 0.3%–0.8%). Check exclusions — many policies exclude pre-existing damage, so a pre-shipment inspection report is essential to prove the car's condition at loading. Incoterms define who bears risk and cost at each stage: 1. FOB (Free On Board): exporter pays until the car is loaded on the vessel; risk passes to you at that point. You pay ocean freight and insurance. Common and usually cheapest if you have your own freight forwarder. 2. CIF (Cost, Insurance and Freight): exporter pays freight and minimum insurance to your port. Convenient but the insurance coverage is basic — consider topping it up. 3. EXW (Ex Works): you handle everything from the exporter's yard; only choose this if you have a trusted agent in China. Put the agreed Incoterm and port clearly in the contract, and never release final payment before the Bill of Lading is issued.

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.

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.
