What are the precautions for purchasing a new car?

[Nguyen]

When purchasing a new car, pay attention to the vehicle's manufacturing time, check the glass markings, and inspect the inner wall of the exhaust pipe. Check the vehicle's manufacturing time: On the nameplate of the co-driver's door, there is the vehicle's manufacturing date. For domestic cars, it should not exceed three months, and for imported cars, it should not exceed six months. Otherwise, it might be a stock car. Check the glass markings: Check if the glass markings are consistent with the original factory. The production date should not be later than the factory's date. The numbers represent the year, and the dots represent the month. If the dot is in front, subtract it from 7; if it's at the back, subtract it from 13. If the markings on all four glasses are different, it might be an accident car. Check the inner wall of the exhaust pipe: The mileage should preferably not exceed 50 kilometers. Inspect the inner wall of the exhaust pipe for any black traces. If it's noticeably black, it might be a test-drive car. Check the car paint under both direct and indirect light for scratches. Small dents should be repainted smoothly.
