A cold start reveals problems that a warm engine hides. Ask your inspection agent to perform and film this sequence. First, the start itself: the engine should crank smoothly and settle into a stable idle within a few seconds. Extended cranking, blue or white smoke, or a lumpy idle suggest worn internals or head-gasket issues. Second, listen for timing-chain rattle or metallic tapping in the first ten seconds — cold top-end noise often means deferred maintenance. Third, watch the exhaust on a cold morning: brief white vapor is normal in winter, but persistent blue smoke means oil burning, and sweet-smelling white smoke can indicate coolant leaking into the cylinders. Fourth, have the inspector scan the OBD system right after the cold start; misfire counters and fuel-trim values are most honest when the engine is cold. Ask for a continuous, timestamped video from outside the car before startup through at least five minutes of idling, so you can verify the engine really was cold.

It depends on the brand, so verify before buying: 1. OTA updates: most newer Chinese EVs update over the air, but some brands tie updates to the region of registration—an exported car may stop receiving them or stay on China firmware. 2. Companion apps: functions like remote climate, charging status, and location often require a Chinese phone number or mainland server access; abroad they may work partially or not at all. 3. Language and units: check the infotainment can switch to your language and your units (miles/km). Ask the exporter to demonstrate the app functions live on video before purchase, and get written confirmation of what will work after export. For the battery, request an SOH (state of health) report—battery replacement is far costlier than any software limitation.

Verify if the vehicle model is within the manufacturer's EU certification scope. If not, contact the certification company for single model certification; otherwise, it cannot be registered in Europe.
