Very bad. The maintenance cost of second-hand trucks in Ningxia is high, so it is necessary to strictly check before buying, test the performance after buying and maintain the parts. It takes a lot of energy and time, and the second-hand trucks are also very poor. When dealing with second-hand trucks, we should pay attention to whether the other party sells license plates. If you sell a license plate, you should strictly examine the license plate, otherwise you should be investigated for the legal responsibility of illegally buying a license plate.
