How to identify the quality of second-hand cars. Tips for looking at cars when buying second-hand cars.

More and more people own cars now. For people with average budgets or those who have just obtained a driver's license, second-hand cars have become an option. The price is lower and you don’t have to worry too much. However, not all second-hand cars can be purchased. You must also check many aspects to rule out faulty cars, accident cars, etc. Let’s take a look at some basic identification methods.

How to identify the quality of second-hand cars

First check the appearance of the second-hand car to see whether the color and gloss of the paint on the body are uniform, and whether the strips and edges are stained with paint. If any of the above conditions are present, you can tell that the exterior of the vehicle has been repainted and may have scratches or sheet metal.

Then open the hood, check whether the screws on the hood, fenders and water tank frame have been twisted, and observe the welding points of the longitudinal beam joints on the fenders. The original welded joint should be slightly rounded and slightly sunken. If it is found that the solder joints are protruding, there are spot welds of different sizes, the solder joints are rough and not smooth, and the arrangement is irregular and uneven, it means that it has been welded twice, indicating that it has been hit before.

Open the door, remove the four door seals, and check whether the solder joints on the main body are really round and slightly concave, and whether they are irregular and uneven. If so, it means that they have been welded twice. In addition, check the lower door beam for signs of cutting or repair.

Check the trunk, check whether the left and right wings are connected to the edge banding tape, open the trunk wing trim and spare tire floor to see if there are any traces of sheet metal.

The above methods can easily identify accident cars. If you need to buy a second-hand car, it is recommended to go through formal and guaranteed channels.

Tips for looking at cars when buying a second-hand car

1. Whether the procedures are complete and normal. Carefully confirm the body number and engine number.

2. Whether there is any damage to the exterior structure of the car body. Choose a brightly lit place and observe the car at 45° to see whether there are color differences, scratches and hidden dark pits on the body. In addition, check whether the ribs of the body are straight. The areas where the ribs are not straight must have been spray painted on the sheet metal.

3. Whether there are blisters and traces of fire.

4. Check whether the engine and gearbox have oil leakage, maintenance and abnormal noise.

When checking the engine, be sure to open the front cover switch of the car so that the engine is starting. The normal sound of the engine should be smooth and low. If there is any abnormal noise, it means there is something wrong with the engine.

Also pay attention to whether there are traces of oil leakage on the chassis.

5. Check whether the gear switching and function switch keys in the car are normal, and whether the airbag is original.

6. Test drive. During the test drive, it depends on whether the clutch, gear shifting, and speed increase can be completed in one fell swoop, and whether the gearbox is flexible. Switch back and forth between acceleration and deceleration to see if the car makes particularly loud noises. These can provide a more complete understanding of the performance of used cars.

What kind of second-hand cars cannot be bought

The first is the problem car. A problem car refers to a vehicle that has had problems such as accidents, sparkling water, fires, or renovations in the past. This type of operation cannot guarantee subsequent safety.

The second is a car from a car rental company. Although this type of car looks good and needs regular maintenance, it is often used intensively and for a long time. The wear and performance loss is much faster than that of a family car, and the service life is greatly shortened. It is better to buy a new car.

Then there are models that have been discontinued. It is difficult to find suitable spare parts for discontinued cars. If parts need to be replaced or repairs are required in an accident, routine maintenance will be inconvenient, which directly affects the normal use of the vehicle. Therefore, it is necessary to consider the later maintenance costs and convenience of maintenance of the vehicle.
