Nowadays, the used car market is becoming increasingly sophisticated. A variety of models and diversified trading methods are convenient for modern car trading. In recent years, the sale of second-hand trucks is also very frequent, so how to choose affordable and high-performance second-hand cars? Trucks have also become a key issue. The following are some of the factors that need to be noted in the assessment of second-hand trucks. When a second-hand truck is placed in front of us, we must not only see the appearance it presents to us, but also pay attention to whether the car is legal. This requires the seller to present the relevant voucher for a legally-sold used car. Not only my ID card, but also the vouchers and invoices for car purchases, as well as the insurance on the car, should be shown to the buyer without reservation. After both parties confirm the legitimacy of the vehicle, the formal evaluation of the used car begins. truck. Checking the length of life of a used truck requires a detailed inspection of each part. The most basic is to observe whether the color of the paint on the surface of the car is intact and whether the paint is faded. The second is to check if the glass of the window is smooth and there are no cracks. In particular, it is impossible to ignore whether the specifications of each glass are the same. If it is not the same, it may indicate that the glass may be damaged due to an accident before the truck. Then don't forget to check the position of the truck, such as the signs of friction on the wheels, whether there are obvious cracks, whether the height of the car body is the same, etc., to determine the age and damage of the used trucks. Finally, we must not forget that in order to check the performance of second-hand trucks , it is necessary to have a certain control on the vehicle. For example, whether the control switch of the truck reflects the sensitivity, the steering wheel of the truck is intact, and the wiper and indicator light are controlled. Is it smooth? Of course, the above can only reflect the local performance of the truck. To make a more accurate judgment, it is necessary to check the engine of the truck, open the cover of the engine, observe the surface for any traces of oil, and listen to the machine when it is started. There is no noise and so on. Only by checking these can we better evaluate the performance of used trucks.
