We maintain an absolute skeptical attitude. In addition to regular visual inspections, we focus on checking for sediment accumulation around the sunroof drainage channels and look for water stains under the A-pillar trim and front floor mats. This is the only effective physical evidence to determine if the sunroof drainage holes are blocked, leading to hidden leaks.

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.

Rules differ by country. Many markets limit the age of imported used cars (commonly 3-5 years), require left-hand drive, and set minimum emission standards such as Euro 4, 5 or 6. Some regions additionally require a local conformity certificate before the car arrives. Practical steps before any deposit: check your customs authority's official website, or spend 20 minutes with a local customs broker who imports vehicles regularly; give the exporter your country's requirements and the VIN, and ask for proof of the car's emission level (China's standards map roughly to Euro equivalents); confirm the exact model was legally exportable from China. A short verification call at the start can prevent the car being refused entry — or impounded — months later.
