Identifying a used car is a very technical job. Even an advanced used car appraisal professional needs to use professional tools and equipment to detect key positions for used car identification in order to more reasonably assess the true value of the vehicle being inspected. However, as an ordinary consumer whose car knowledge is relatively lacking, how to buy a second-hand car that is not being “fudgedâ€, Huacai used car market appraisers teach ordinary consumers a few easy-to-learn methods.
Check appearance
First of all, with the naked eye to check the body paint color is the same, whether the curvature of the two sides of the surface is smooth, 30 ° to 45 ° angle to see if the paint surface reflection is reasonable, if different, the vehicle must be repaired, and the repair level is poor. Then look at whether the joints between the engine cover and the fenders on both sides are average; whether the gaps on the door edges are the same; whether the headlights, the rear tail combination lamp and the metal connection gap are the same, and whether the old and new degrees are the same. If the gap is large, it is likely to be traumatic.
Then the consumer can observe whether the logo of each piece of glass is the same brand. Turn on and off all doors, open the door to 45° to 60°, and close the door with normal force. Observe whether the door can be closed tightly, and whether the sound is the same and the strength is the same.
Finally, observe the degree of tire wear, whether the brand is the same and whether the pattern is the same. If there is any difference, it must be replaced after the vehicle is purchased to ensure the safety of the vehicle. In addition, due to the side of the parking hub is easily damaged by the roadside, especially the hub, tire joints severely damaged, dynamic balance is difficult to repair.
　
Check inside the car
When consumers look at the interiors, they must check whether the seats and linings are clean and tidy and whether they have been replaced or disassembled; in particular, check the floor of the car to determine if it is a soaking vehicle. In addition, check whether the head restraints and trim pieces in the car are complete; whether each switch is controlled smoothly or not.
In addition, consumers can view the vehicle's problems through the in-vehicle lights. Open the key door and observe whether the indicator lamp display is normal and whether there is a lack of display. Most of the current EFI vehicles have fault warning light prompts. When the key door is opened, each indicator light should be on. If there is no indicator light, the vehicle owner is likely to have the fault is not ruled out, and the bulb of the indicator light is intentionally removed. Confused to see and hear.

Test driving experience
If consumers have conditions, try to drive as much as possible so that they can better understand the performance of the vehicle.
When starting, the engine is easy to start, which can refer to the experience of consumers driving. If the starting sound is heavy, there is a problem with the motor, battery or related machinery. After starting, first check whether the steering wheel (with power assist) is consistent with the strength of the left and right wheels and whether the steering angle is reasonable.
In addition, there are different ways of judging depending on the type of transmission. If it is a manual transmission, first determine the clutch plate needs to be replaced by the mileage of the drive and the level of the clutch. Then look at whether the shift is smooth or not. If the shift is not on the block, it means that the synchronizer wears badly and may require maintenance; If it is an automatic transmission, it is mainly determined by whether the automatic transmission shifts smoothly when shifting, and whether there is a strong sense of frustration.
In the process of driving, we must pay attention to the location of car noise and the size of the sound, to determine the car's degree of sealing and sound insulation. Also note if there are abnormal sounds in the engine, transmission, and suspension, and if so, you should check the abnormal sounds further.
When checking the brake system, it mainly depends on the braking distance of the vehicle and whether the brakes are deviated or not. When the vehicle is braked, the vehicle will be shaken. It is also necessary to pay attention to whether the ABS anti-lock device will be dragged.
The quality of the suspension system directly affects the safety of the vehicle. The conventional method is to select a wheel to press down firmly, and then release it to see its reset. If the fluctuation is relatively large, it means there is a problem with the shock absorber. There is no fluctuation in one reset, which means that the state of the shock absorber is still better. If you pass over the hurdle, the car swings like a ship, indicating that the shock absorber has a problem.
The appraisers remind consumers: “The test car service is rarely available in the used car market, and it can only allow customers to drive around in the trading area and can't feel the actual performance of the vehicle. Therefore, it is best for consumers to pick the car. An older driver, who knows more about the car, can help him to check the gates, or to use the testing center of the used vehicle to test the equipment. This will be more secure."
