1. Bring relevant documents before picking up the car, such as advance payment receipt, appointment contract, ID card, driver's license, etc. 2. When picking up the car, it is best to put two cars with the same style side by side and ignite at the same time, so that the sound of the engine can be compared. Try to pick up the car when it is sunny, so as to check the appearance. Pay attention when checking the appearance. When some stains on the car are not sure whether they are scratches, it is best to find a wet cloth to wipe them, and remember not to dig with your fingers! ! ! ! ! ! 4. Because many friends are picking up the car for the first time or are not of the same type as the previous car, you must take pains to understand the problems closely related to driving now, such as how to open the hood and fuel tank, how to use the automatic door lock and air conditioner, how to adjust the seat and audition afterwards, the ideal speed (88/KM) during the running-in period, etc ... If you don't understand these, you will cause yourself great trouble, so don't be embarrassed to ask, and don't be embarrassed to ask. ! ! In addition, it is best to go together when picking up the car, so that the question is more comprehensive. 5. Pay attention to the mileage reading of the odometer when picking up the car: generally 8- 10 km, and see if there are any sundries on the radiator of the water tank! Whether the seat protection package and plastic paper at the front of the car are complete! Whether there is dirt on the driver's seat and the instrument inside the car! (Feeling unclean) 6. When picking up the order car, pay attention to whether there is too long time between the delivery date and the delivery date. If the time is too long, this car may be a display car (placed in the exhibition hall for guests to display)! Or renovate the car (test drive)! 7. Remember to ask the production date and transportation date when picking up the car, and compare the mentioned vehicles in detail! 8. After buying a car, hand it over to the 4S shop for licensing and various procedures. Remember to copy the odometer, and don't drive around selling it! 9. Look at the appearance: When choosing a new car, you can let two cars of the same model choose. Pay attention to body cracks and paint. This observation is skillful. You can focus on the gap between the bumper and the body, the gap between the door and the front and rear bumper, and open the door to see if the paint inside and outside is colorless or not. For paint surface, the requirements for external light conditions are relatively high. The best observation light is sunlight, and nothing can hide it. If you choose a car in the exhibition hall, you can observe it diagonally in the direction of the sun, which has the same effect. The qualified paint surface should be smooth and free from orange peel ripple defects, and there should be no color difference between the bumper and the easily damaged parts such as the body, the outer edge of the door and the left and right exterior rearview mirrors. For metallic paint and pearlescent paint, it can also be judged by observing the uniformity of aluminum powder or mica particles in the paint. After the above procedures are completed, the appearance of this car is qualified. 10. Look at the mechanical part: Of course, the first thing to look at is the engine. A well-run engine should be oil-free, with quick and sensitive response when starting, stable operation without jitter, stable sound and no sharp noise or non-fixed frequency noise. When the car is cold, the idle speed is slightly higher. According to the tachometer, it is about 1000 rpm. After the water temperature rises, the idle speed drops to about 780 rpm. At this point, when refueling lightly, you should feel sensitive, without knocking or loosening. Touch the engine cover with your hands, and there is no obvious vibration. When you are sitting in the car, you can hardly hear the working noise of the engine. If you are not sure about the above aspects, it is also a good way to compare two engines running at the same time. The oil-filled part of the engine should be clean and free of oil pollution. Even if there is no obvious oil stain, the situation of sticking dust is equivalent to this. Only the oily parts will stick to dust. For other mechanical parts, this method can also be used to assist judgment. Check the three oils and two fluids of the engine (three oils: engine oil, brake oil and direction booster oil). Level of two liquids: coolant, windshield washer fluid), and then check the battery. The new car can know the battery status by observing the battery status indicator. If it is green, the battery is in good condition and fully charged. If it is black or white, the battery is low or even damaged. It is best to charge as soon as possible. 1 1. Look at the ground: after looking at the engine, it is better to run for a while and then look down at the car. Seeing the signs of waterless oil stains is helpful to judge some hidden faults. Under normal circumstances, there should be no water leakage and oil leakage in other parts except the dripping from the exhaust pipe. 12. Look at the tire: A normal new car tire should have no damage to the sidewall, especially the front sidewall. There are no nail marks on the tread, and the front and rear tires are the best. At least the fetal hair on the rear wheel should be visible. If the four wheels are bare, there is no fetal hair, and the local road surface is not bad, then think twice. 13. Look at the door and the wiper: qualified doors should be opened and closed evenly without abnormal sound. The sealant skin is intact, and the obvious sealing effect can be felt when the door is closed, and the door will have similar suction force to close the door in the last stroke. The paint on the lower edge of the door frame is intact. If it is found to be worn or dirty, it is necessary to consider whether the storage conditions of this car are ideal. Electric glass design has four anti-pinch doors. 14. Look at the interior: there is nothing else in the interior, and cleanliness comes first. The interior should be clean, especially the parts that are easy to get dirty, such as the inner handle and the inner light (pictured). Electrical or mechanical parts should be light and flexible, and operate without noise. The floor of the carriage is clean and there is no water stain. Check the lights in the car. The lights should work normally and be in good condition. Remove the white cover of the seat package on site, check whether the original leather seat cover is sick, and use the easily damaged parts such as water cup holder and glasses box cover as many times as possible to ensure the function is intact. 15. Look at small objects: All sunshade lights need to be checked, because these two small objects are usually overlooked. Because the ashtray cover is designed with shock absorption, it should also be checked. Pay attention to whether the switch is pushing the movable cover, and don't pull it when it is closed. If it is broken, you have to pay for it yourself. Check the cigarette lighter of 16. Look at the skylight: try the skylight to see if it is abnormal or rough. Check the curtains in the back seat and the central armrest passage. 17. Listen to the sound system, power seat and reversing radar, and see if it works. If an antenna is installed and there is no antenna, the reception effect of the radio will be poor. 18. Look at the key: a key code bar and a plastic key mold, which are used for matching keys and emergency. Ignite the fire, and after turning on the power supply, self-check the electronic system in the car 19. Look at the lights: after the new car is tested, you can check the lights when you return to the exhibition hall. Check all kinds of lights, check whether the fuel tank cover is in good condition and effective, and ask how to open it. 20. Look at the tools: Don't forget, there is also a triangle sign on the back of the trunk lid, which is orange and needs to be checked to avoid learning bad when using it. Long-term storage of spare tire has high air pressure, which is not suitable for long-term use. It should be replaced in time after conditional tire repair. Check vehicle-mounted tools: jack, dual-purpose screwdriver, small wrench, wheel cover removal hook, tire changing positioning bolt. No more, no less, you'd better try. 2 1. Look at the information: there are instructions and VCD discs in the information package. The manual must be put aside. This is the original record of maintenance, which is very useful for claims within the claim period. If it is lost, it can't be recovered. Check the certificate, which is a major event related to the new car entering the home. 22. Check whether the VIN code and engine number of the certificate are consistent with the original car; Whether the steel seal number is neat and whether there are any traces of modification. Collect the motor vehicle parameter list and free maintenance card. Be sure to tear it up before entering the house, so as not to be taken away and unable to get it back, and there will be one less chance of free maintenance. There are three invoices for new cars, which should be special invoices for motor vehicles. 23. Other notes: 1) The factory date marks the date when the automobile is assembled from the production line. It is usually marked on a small aluminum plate under the hood. If you see that this date is close to the date when you bought the car, it means that this car is relatively new. If this date is far from the date when you bought the car, there may be a problem. Because the interval is too long, for example, vehicles with a backlog of more than one year may be repeatedly selected by others but cannot be sold. At the same time, if it is placed in the open air and exposed to wind and rain, it will involve the aging of batteries, wiper blades and lubricating oil without maintenance. 2) When you get into the cab, you can try whether the doors and windows are lifted smoothly, whether there is rust on the corners, and whether there is dirt on the seat. Shake the steering wheel by hand, and there should be no jumping up and down. When turning the steering wheel left and right, there should be a little free travel, which should meet the requirements of the instruction manual and generally not exceed 15 degrees. Whether the instrument and auxiliary instrument table are assembled neatly and skewed. Try to see if the switch of gadgets such as toolbox and ashtray in the car is smooth. 3) The center console panel is prone to problems, and dealers sometimes get thicker. If you don't pay attention to scratch the paint on the panel, you can bring your own CD. [b] To put it simply: 1. Production date, preferably within 1 month. 2. The mileage is within 10km. 3. Check whether there are scratches inside the paint. Look as carefully as possible. If it's a driven car, it usually leaves clues. 4. Insist on hanging and watching the scene. (4SMM will say that the regulations can't hold, and this is an excuse, afraid of trouble) Be firm. Generally, 4SMM will compromise, and carefully check the chassis for stolen goods and scratches. 5. Listen to the engine sound at idle speed. As long as you (no matter how good you are) think it is abnormal, there is no room for discussion to question it. 6. Give it a try. 7. Check the accessories on board.
