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.

Usually yes, but with conditions. The seller must transfer the vehicle's account binding to you — without that, the app stays locked to the previous owner. Ask for a screen recording showing the unbinding and re-binding process. OTA updates and remote functions depend on the manufacturer keeping servers accessible from your region. Most major brands now support overseas accounts, but features like voice assistants or map data may be limited outside China. In-car navigation may default to Chinese maps, so plan to use Android Auto, CarPlay, or phone mirroring instead. Before purchase, confirm with the exporter in writing: which connected functions work in your country, and whether a regional account conversion is included in the price.

Obtaining precise internal resistance at different SOC levels requires disassembling the battery pack and connecting it to a professional charge-discharge cabinet for several days of cycling tests. This is beyond the scope of non-destructive used car inspections; we only provide real-time estimated internal resistance data based on OBD port readings.
