The price of used cars is not worth buying. First, look at the specific car condition, whether the whole car has undergone substantial remodeling and soaking, and check the following points in terms of performance: 1. Whether it can be started smoothly and whether there is jitter and noise; 2. Check the clutch and transmission for smooth shifting, flexible and smooth starting, bumping, gear jumping, jamming and abnormal sound; 3. Check the power and sliding performance to see if the vehicle accelerates from the initial speed to 100 km, then slow down and stop to see if it is smooth and slippery. The second is to look at the years, kilometers and prices, and fully measure whether it is worth buying.
