Most models adjust through the central control screen menu, while a few models (like some BYD or MG) retain physical levers or paddles on the center console or steering wheel. We will check if the drag feel when the system engages is linearly normal.

China's vehicle data is less centralized than in the US or Europe, but you can still verify a lot: 1. Ask the exporter for the VIN and order a third-party history report from Chinese services; they aggregate insurance claims and repair records. 2. Cross-check the registration date on the title with the odometer—a 3-year-old car showing 30,000 km but registered as a ride-hailing vehicle is a red flag. 3. Request maintenance records from the brand's dealer network; digital records are increasingly common. 4. Verify the seller legally owns the car: the registration certificate name should match the exporter's business license. Gaps are common, so treat the history report as one input, not proof. Combine it with an independent pre-purchase inspection, and hold back part of the payment until the inspection passes.

As rubber seals age, "slight oil seepage (oil stains but no dripping)" is very common in used cars and is not considered a major fault. Our recommendation is: as long as the oil level does not drop abnormally, just clean and monitor it regularly after arrival, without the need to immediately incur high costs to disassemble and replace the seals.
