- What year is it? What’s the real mileage?
- Determine the completeness of the procedures of the vehicle condition, whether the transfer
- Inquire about violations and unpaid fees
- Make clear to have year of careful, road cost, insurance expired did not have
- Has the vehicle frame and engine number been changed
- Whether it is corroded or corroded, whether the car surface is original paint
- Efi? Carburetor? Are emissions up to standard?
- There are no major accident repair traces
- Compared with the new car, we can see whether the engine is running smoothly, whether the engine is leaking oil, whether there is deviation or abnormal sound, whether the acceleration is smooth, etc
- Car purchase time: the vehicle placed in a night, some cars will not be easy to start, traces of oil leakage on the ground, that the electrical system or oil system problems, therefore, the vehicle in the morning can reflect its basic performance, especially in the summer, but also catch early not catch late! Summer to carry out a thorough inspection of air conditioning, afternoon high temperature, the best to understand the working ability of air conditioning, therefore, choose the car first to choose the right opportunity, grasp the opportunity to “check” to the baby.
-Factory date: Because China has clear regulations on the service life of vehicles, generally 10 years, the longest is not more than 14 years, therefore, when buying second-hand cars, it is necessary to find out the factory time of the vehicle, so as not to buy back the vehicle will be scrapped, the factory time of the vehicle can generally be found out through the vehicle plate, or the registration record of the original user. The most accurate is to find the technical information of the vehicle to understand the method.
-Mileage: usually the service life of the car and the use of time and mileage has a very direct relationship, generally in the driving 150-250,000 kilometers later, the performance of the car will be significantly reduced, the technical status will become worse, the need to constantly repair or replace parts. Check car mileage can be through the observation on the clutch pedal and brake pedal rubber wear, the service life of the general manual transmission clutch pedal for 3 ~ 50000 KM, and automatic transmission pedal life is 8 ~ 100000 KM, in addition, according to the wear condition of the tire also can judge out the general range of the car, The normal service life of automobile tires is 100,000-120,000km, but abnormal wear may greatly reduce the service life of tires.
-Body appearance: Buy used cars you can’t remember by the first impression feel models in fashion, no scratch, no surface impulse buy, be sure to carefully observe the car appearance, can be in the order from outside to inside, look carefully paint, general factory paint uniform texture, color coordination, and after a repair shop to repair the car paint, paint colour or thickness will doesn’t tally with the surrounding, also can open the trunk, According to the color of the luggage box can also determine whether the paint has been resprayed, so we should pay attention to the color deviation of the paint and the paint residue on the edge of the rubber seal, but also pay attention to the paint surface of the lower edge of the door, the car longitudinal beam and other areas and whether there is corrosion. In addition, but also to see the front cover, door and the back of the surrounding frame clearance of the degree of uniformity.
-Carefully check body corrosion, length of time of it with the original car use and future life has a lot to do, otherwise, the vehicle to buy back, there will be body jitter, serious welding or repair is needed, but through the inspection door, window, fender, launder, sealing strip and sealing conditions and degree of corrosion, can also open the suitcase and uncovered the first floor mat, Check for leaks on the floor of the suitcase.
-The identification of wear degree mainly depends on the front wheel. If the pattern is flat and the edge has no edges and corners, not only the tire itself is not in good condition, but also the overall condition of the whole car can be very problematic.
-Car interior: in the inspection of car interior, should be checked one by one dashboard, steering wheel function key switch and display lights are intact, good steering wheel in hand shaking, up and down should not have a gap, left and right shaking amplitude should not be too large. Also pay attention to observe whether the door glass can rise and fall freely, whether the sealing is good. The seat surface should be clean and free from damage, and slide smoothly back and forth without obstruction.
-Engine: check the appearance of the engine, identify the traces of oil leakage and water leakage, ignite the engine and observe the color of the exhaust gas. If it is translucent and light gray, it indicates that the engine is in good condition. If the exhaust gas is black, it indicates that the engine is not adjusted well. In addition, can also be identified by sound, sound crisp and strong sense of rhythm is generally a good machine, but there are also some model design is low. In short, the cabin must be clean, no oil leakage, oil seepage phenomenon, sound rhythm is not chaotic. The oil should be viscous and free of metal dust, which shows whether the original owner cared for and maintained the original car.
-Shock absorption and suspension: the available hand will be the car before and after the left and right angles of the pressure, such as relaxed car body can rebound, and can freely jump 2~3 times, that the system is normal, such as abnormal sound or can not automatically jump, that the shock absorber or suspension system spring and other components work poorly, comfort will naturally become poor.
-Trunk: lift the cover, if there is no trace of sheet metal along the edge, it means that the car has been rear-ended, then observe the light reflection and color difference of the rear wing sub-plate (side plate of the trunk).
-Road test check: start, check whether the clutch engagement is smooth, there is no jitter and abnormal sound. Start accelerating in place, step on the accelerator to see whether the speed is sensitive, on the ramp to check whether the speed is strong, if the speed is slow, uphill and no strength, it shows that the engine power is insufficient.
-Transmission system inspection can be through driving neutral taxi, according to the length of the taxi distance to judge the pros and disadvantages of the transmission efficiency.
-Check whether the transmission can feel flexible and smooth when increasing or decreasing gear, whether there is jump gear, clamp gear and abnormal sound.
-Vehicle procedures after checking the various performance and configuration of the car, must check the various procedures of the second-hand car is complete, July will come, a lot of vehicles road maintenance fees, insurance premiums are about to expire, when buying second-hand cars must consider this part of the cost, so as not to cause losses.
-Convenient maintenance is the key Because there are many car manufacturers at present, complex models, some of the vehicle maintenance difficulty is bigger, once appear, fault, will be due to the lack of accessories, cause parking unattended for a long time, give yourself a great inconvenience, so the best choice when choosing a used car models for easy maintenance, can reduce a lot of trouble.
