Identify good used cars

  The residual value of a used car is the residual value of the vehicle, that is, after comprehensive scoring according to the age, maintenance level and performance of the vehicle, to understand the real condition of the vehicle. You can start from the following points:  
1. Find the accident traces and hidden dangers  
  , lift the carpet inside the car, and find out whether there are any flaws in the body below. Look closely at the door to see if it has been repainted. Any new paint will cover up imperfections you don't want people to know about. Check whether the lines of the whole car are smooth: because once the car is scratched or collided, the body lines are the most difficult to repair and symmetrical. Whether the clearance of each part of the vehicle appearance is consistent. Check for an even finish on the paint surface. Whether the sealant of each part of the body is complete. Whether the original car welding point is complete.  
2. Identify the real age of the car
Take a look at the rubber mask on the pedal, which can best reveal the actual age of the vehicle. The service life of a rubber mask is about 30,000 kilometers. There are often people who worry that the original owner will falsify the odometer. There are also ways to check. You can check the latest maintenance invoice or maintenance manual of the car, which should indicate the mileage of the vehicle.  
3. Carefully check the tire wear degree,  
  especially the front wheel. If the pattern is flat and the edges have no edges and corners, it shows that the original owner's driving habits are rough. In this way, not only the tire itself is in poor condition, but it also reveals that the overall condition of the whole vehicle will be very problematic.  
4. Condition  
  of the body Turn around the body patiently for a few more laps, and carefully observe the edges of the fenders and the axles to see if the parts are worn and weathered by the wind and the sun.  
5. Engine appearance and operation  
  Check the appearance of the engine and identify the traces of oil leakage and water leakage. Ignite the engine and observe the color of the exhaust gas. If the exhaust gas is translucent light gray, it means it is in good condition; if it is black, it means the engine is not well adjusted; blue means the engine is very tired; white means the cylinder head gasket will be scrapped.
6. Check the driving performance of the vehicle  
  If you want to check the status of the clutch, I will teach you a trick. When starting, put the transmission in the third gear instead of the usual first gear. If the engine does not turn off as normal, it means that the clutch is aging.  
  Afterwards, drive for a while, and continue to listen carefully to the sound of the engine as the engine warms up to the proper temperature. Change the speed as often as possible to see how the car reacts when accelerating and decelerating. If the car body and steering wheel shake when the speed is high, it is very bad. When purchasing an old motor vehicle with a long year, it is necessary to compare the price difference and consider the maintenance cost.
