Generally speaking, it is not difficult to buy used cars, but there are several psychological needs to understand: on the constitutional point of view, used cars because of the older cars in the new year, the aging of all parts of the machinery, loose, imbalance, these are nothing Avoiding it, it is not possible to look at it with too harsh a mentality, but rather how much the budget should be used to value the value. Of course, the price or year of the original car (years of the car), the mileage of the car, and the car Demand of the market (popularity) or additional equipment attached to purchases are all factors that affect the price of used cars, which is the so-called "market price."  Steps/methods  Formula One: The market price can be used as an estimate but it depends on the actual conditions. The above-mentioned so-called market prices may actually be traced, but they are still based on approximate estimates. They are calculated in a new car, and they are discounted by approximately 30% within a year after being listed, and then re-inflated within two years. A discount of 20%, and a discount of 15% in the first year, depending on the condition of the car (because the vehicle condition changes with the driver's habits, maintenance concepts, etc.). It is worth mentioning that the above-mentioned estimated price is only for reference, and you must not use this method to reduce the price of all vehicle models, because the market price in addition to the vehicle conditions, the popularity of the car Whether this car has been discontinued, the convenience of maintenance, and the price of parts are all factors that affect the market price.  Rule 2: When shopping, don't focus on the appearance of the car. Whether there is an accident or not is what you should be careful about. When you have a general understanding of the market price, let's take a look at the appearance of the body when you get to the eye, but don't think that the appearance of the car just looks at the appearance. In fact, he is looking at whether it is the first step in the accident. The accident vehicle mentioned here is not an ordinary collision, but it is an "accident vehicle" that seriously damages important parts such as the girders and engines. When you look at it, you can check it from the front, door, rear luggage compartment, etc. When observing the front, the engine cover is used as the main body, in addition to the need to carefully check the degree of closeness with the fender or the gap between the cover and the left and right leaves (do not have different sizes), the engine cover and head The lights are uneven and the clearance between the hood and the windshield is the same or leave the glue paint of the original vehicle, which is the focus of the inspection.  Rule 3: You can check the engine room from a few points. The inspection of the engine room is the key point. When you open the hood, check the inside of the engine cover. If there are traces of baked paint, it means that the probability of collision of the cover is not low, because most people will not There is nothing else to paint in this place, because it does not have aesthetic value. Then, you can see from the upper beam of the engine room (also the I-beam above the tank cover), the two longitudinal beams below the engine body or the two internal beams of the engine room commonly known as "inside return". There should be traces of circular spot welding. If there are out-of-round or uneven spot weld shapes, they may be subjected to impact. The connection of each steel plate is also the focus of inspection, whether the waterproof rubber strip is smooth, it is also the basis for judging whether the car has love or injury.  Rule 4 for picking up the car: Try to check if the car door is smooth and sound-free. The opening of the trunk is also the focus of inspection. Look from the door frame and B-pillar to see if it is a straight line. If there is no wave (commonly known as orange peel), it means there is no big problem with this car. In addition, you can check from the door. When the door is not open, you can first see if the joints of the door are flat. If the closeness of the joint is smooth, there is no big problem with this car, but you can't conclude that the car is OK. Then check the A, B and C pillars when the door is open, that is, whether the door frame is in a straight line. If there is a similar wave (commonly known as the orange peel), it means that the car has gold over it. Whether black plastic strips are open or not, whether or not there is a nail mark near the door when the original car is engaged, if there is a trace, this car is the original car. If not, it means the car has baked. Finally, the door can be switched back and forth to check the smoothness of the opening of the door. It is extremely smooth when there is no noise or when it is turned on. It means that the car is not a big problem, but it does not mean that the car is free! The left and right sheet metal parts at the opening of the luggage compartment or the joints with the post-protection. When viewing, first open the carpet under the luggage box and check whether there are any traces of welding at the place. Even though the current sheet metal technology is very advanced, However, as long as you are careful, you must check the clues, but to remind you that as long as it is not a serious accident car, you must not have too harsh requirements, but should be measured at the price of the car to buy Value, otherwise don't blame the author when you are expelled.  Formula 5: Water, oil, and gas should also be inspected to determine the operation of the first heavy engine. After viewing the structure of the static body, we will discuss the so-called condition of the car. When the engine is not started, we recommend that you first check the tank water in the engine room to see if there is enough water, or there is no water rust or water leakage. In addition, you can use the oil dipstick to check whether the amount of oil is enough (should be more than five minutes before the engine is started or after the engine is stopped), whether the oil is clean and there is no gas. The engine oil is not clean and small (color is cloudy, and impurities are serious). If it contains water, it can be serious. This kind of engine draught will make the water and engine oil mix and show a turbulent white color. The damage to the engine is very great. If there is such a situation, it is recommended that you do not touch it. The trick is to check if there are some things like brake oil, battery water, wiper water, tire pressure...etc. The water tank is used to check if the I-beam above the tank cover is flat and there are traces of circular spot welding, which can be used as the basis for judging whether this part has been injured or not. Whether the waterproof strip is smooth or not, whether there are signs of passive hands or feet can indicate whether or not these parts of the vehicle have been injured. Next is the so-called inspection of the condition of the vehicle. When it is started, it is to see if it is smooth and well started. Then it is discharged into the forward (D) position to see if the vibration will be too severe (something may be too low speed, unstable engine bracket, four One cylinder in the cylinder is not moving, etc.). Moreover, it is to turn on the air-conditioning to try to get cold and cold, and also to observe the jittery situation. If there is a jittery situation when the air-conditioning is not turned on, the air-conditioning will be more jittery. Severe, if only a slight shake, I believe it is inevitable, because this situation may occur in new cars, let alone used cars? If there is a buzzing noise in the air, it may be that the compressor is in a condition where the belt is jerky, heavily dragged or broken. Then it is to check some electric sound and light equipment, such as electric windows, audio, wipers or left and right direction lights, warning lights, brake lights and so on. If you cooperate with the actual dynamic test, I believe that you will let the car status has unexpected results.  Rule 6 for picking cars: Observe the coordination of various parts when observing the road and don't forget After the dynamic inspection of the chassis of the vehicle is completed, the condition of the road of the vehicle is analyzed, such as whether there will be cracking noises in various parts when the vehicle is started, and the rebound reaction of the car when it encounters a pit, when the cornering turns The reaction to pulling ... and so on are all things you can't ignore. If you can, we suggest that when you try it out, you may wish to find a good friend to follow and see if there is any meandering or erratic situation when the car is on the road, so as to provide you with the opinions after the trial. Another thing to tell you is that the average consumer is buying a used car where it is often overlooked - that is, the "chassis". Because of its inconvenient viewing, consumers often find themselves in trouble and ignore it. The loss of equity was lost. In the final analysis, its importance is comparable to the human skeleton. Any damage may end the life of a vehicle early. Therefore, it must be taken carelessly. The chassis is often ignored by used car owners, and it is not easy to replace when it is damaged. Master repairs can only be tinkering, so as long as you snack, you will be able to come up with clues, and because the impact of the chassis on the car structure tension, resistance and other great, in addition to the engine after the inspection of the second major focus, but also Another basis for avoiding the purchase of accident vehicles is indispensable. After seeing the chassis roughly, don't forget! The protagonist in the chassis, the "girder", will not only greatly reduce the safety if the girder has been injured, but may also require you to spend a lot of money to heal it. It is recommended that if you can, look for a home repair shop nearby. , Put the car up to give it a good pulse. In addition to this, it is also possible to check the situation at each link incidentally to see if the screws are loose or not, and if there is any oil leakage in the joints, if the vehicle cannot be lifted up, it can be launched for several tens of minutes. Check the floor of the car body, whether there is oil on the floor. If you ask for a test to see if there is a noise in the chassis, remember! Can not open the sound but also to close the window as much as possible, one can be free from the interference of music and wind chorus to you, and the other is through a quiet car room to let you make a judgment on the source of the sound. But when you buy a "pan-tube car," even if you have a thousand sad reasons, you can only swallow it with tears. 1. Door handles, door maps, driver seat adjustments and twists can all be used to determine the driving habits of the previous owner and whether the car has ever encountered many people. 2. Check whether there is any repair of the chassis, welding traces are the benefits of using the vehicle for high viewing, and the inspection of the beam, whether the oil tank, tubing or oil leakage can be checked. 3. After opening the sub-roof cover carpet, carefully check the steel part of the luggage compartment. Whether the color, lacquer, spot welding marks are out of round or of different sizes can be used as a basis for judging whether there is any impact.  Rule 7: The interior can be used to judge the original owner's driving habits. As for the interior, the view of seat adjustment twist can be used as a basis for judging how many people have drove this car. According to common sense, when different owners are driving the same car, the chances of moving forward and backward are necessarily much higher due to different postures. If the slide rail fixing pin of the adjusting button is stuck or cannot be fixed, the situation will be much higher, but this is only for reference and not all. In addition, from a few small details, we can perceive the habits of the previous owners, such as the compartments, the left and right side of the door, and the recessed grooves. correct! Whether the car roof can have yellow scale or not, can also determine whether the original owner has the habit of smoking in the car room. The most important thing is! It is from the carpet in the car interior, so it can be used to check whether the car is a “water squeezing carâ€, because the rain will often penetrate the waterproof rubber strip and penetrate into the floor of the car room. If there is such a situation or the tightness of the waterproof rubber strip Poor, there is the possibility of forming a water tanker, so you can not carelessly choose, if it really, advise you to quickly find another car is.  Picking Guideline No. 8: Avoid Buying Through Used Cars There are also other ways to identify special vehicles. In addition, the average consumer is also afraid to buy cars that have encountered “usedâ€, such as taxis and sports cars, because these cars may look at birth certificates (years). It is not old, but after a special passing (such as intense driving in the arena, long-term loading, walking and stopping), it is difficult to predict when these "internal injuries" will recur. Therefore, you must be cautious when you purchase, or you can check from the following points: In terms of sports cars, due to the installation of the roll cage, there will be traces of holes that have been controlled in the car room. The taxi can be judged from the engine mileage, the elasticity of the rear passenger seat, the rear ashtray, the rear door handle, the smoothness of the rear door opening, etc., can be used as reference.
