Many connected features are tied to the car's original market. Start with the basics: the infotainment language, navigation maps and voice assistant may only support Chinese, and some systems require a local SIM or account that cannot be transferred to overseas owners. For driver-assistance systems, check whether the model relies on hardware that works without Chinese map data. Lane keeping and adaptive cruise usually work abroad, but map-dependent features like highway pilot may not. Ask the seller to test each key function on video before shipment: boot-up, touchscreen response, app connectivity and over-the-air update status. Also confirm the battery management system and motor controllers have no region locks. Get written confirmation that the features you are paying for are functional in your destination country, and keep that document with the purchase contract.

Many car owners do not have their first maintenance done at authorized dealerships, leading to gaps in early data. In such cases, we do not blindly trust the odometer; instead, we analyze the tire production dates and wear levels, as well as the depth of grooves on the brake disc edges, using the "gold standard" of physical wear to infer the intensity of early use.

A compliant shipment from China includes a standard document set. Verify you receive all of them before the ship departs, because correcting documents mid-transit is slow and expensive. The core set: commercial invoice, bill of lading (original, if your country requires presentation for customs), packing list, certificate of origin, and the export customs declaration. For used cars, also expect the Chinese registration certificate copy, deregistration proof, and a condition/inspection report. Some destinations require additional certificates — GCC states need GSO conformity, EU countries need COC or individual approval, several African nations require BESC/ECTN tracking numbers issued before loading. Your customs broker will typically need the invoice and bill of lading at minimum, plus proof of vehicle age and emissions where age limits apply. Ask your exporter for scanned copies the day the vessel sails, not when it arrives: pre-clearance can cut port storage fees significantly. One caution: the invoice value must match your payment records. Under-declaring to save duties is customs fraud in most countries and risks seizure.
