With more and more people now owning cars, used cars are an option for people on a modest budget or who just got their driver's license. The price is lower, and it doesn't hurt too much. But not all used cars can be bought, but also to check in many aspects, exhaust the broken down car, accident car, etc. Let's take a look at some basic ways to tell.








How to identify the quality of second-hand cars


First check the appearance of the used car, to see whether the paint color and luster of the body is uniform, but also to see whether the rubber strip and edges are stained with paint. If any of these conditions are present, the outer surface of the vehicle can be judged to have been repainted and may have scratches or sheet metal.




Next, the hood is opened, and the screws on the hood, wing panels and tank frame are checked for twisting, and the welding points of the longitudinal beam joints on the wing panels are observed. The original welded joint should be slightly round and slightly sunken. If it is found that the welding spot protrudes, there are different sizes of spot welding, the welding spot is rough and not smooth, irregular and uneven arrangement, it indicates that it has been welded twice, indicating that there was an impact before.




Open the door, remove the four door seals, check whether the welding joint of the body is really round and slightly depressed, whether it is irregular and uneven, if so, it indicates that the second welding. Also, check the door underbeam for cuts or repair marks.




Check the trunk to see if the left and right panels are connected to the edging tape. Open the trunk wing panel trim and spare tire floor to see if there are sheet metal marks.




The above methods can be simple to identify the accident car, if you need to buy a second-hand car, it is recommended to go through a regular, secure channel.

Two, the appearance of the body structure whether there is damage. Choose a well-lit spot and look at the car at 45° to see if there are color differences, scratches and hidden pits.

What kind of used car can't you buy


First, the problem car. A problem car is a vehicle that has been involved in a previous accident, bubble water, fire, renovation, etc. This category does not guarantee subsequent security.




The second is the car rental company. Although this kind of car looks good and is often maintained, but this kind of car often high-intensity long-term use, wear and performance loss is much faster than the family car, the service life is greatly shortened, it is better to buy a new car.
