What should I pay attention to when buying and picking up a new car?

1. When picking up the car, pay attention to the kilometer reading of the odometer: generally, it is 20-80 kilometers, to see whether there are sundries on the radiator of the water tank, whether the seat protection bag and plastic paper at the front of the car are complete, and whether there are dirt on the driver's seat and the instrument inside the car.

2. Pay attention to whether there is too long time between the delivery date and the delivery date when booking a car. If the time is too long, this car may be a display car (put in the exhibition hall for guests to display) or a refurbished car (test drive).

3. Remember to ask the production date and transportation date when picking up the car, and compare the vehicles in detail.

4. after buying a car, hand it over to 4S shop for sales license and various procedures. Remember to copy the odometer, and don't let the sales staff drive around the street.

5, look at the appearance: choose 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.

6. Look at the mechanical part: Of course, the first thing to look at is the engine. A well-run engine should be oil-free, respond quickly and sensitively when starting, run smoothly, sound smoothly, and have no sharp noise or noise with irregular frequency. 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 sit in the car, you can hardly hear the noise of the engine working. 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 dust sticking is equivalent to this, because only the parts where oil sticks 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.

7. Look at the ground: After watching the engine, run for a while and then look down at the ground. 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.

8. Look at the tires: Normal new car tires should have no damage to the tire wall, especially the front tire wall. 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.

9. Watchkeeping: 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.

10, look at the interior: the interior is nothing else, and cleanliness comes first. The interior should be clean, especially the parts that are easy to get dirty, such as interior handles and interior lights. 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.

Car purchase invoice and vehicle certificate are necessary documents for car users, so when buying a car, you must ask the dealer for the car purchase invoice and certificate. Among them, it is necessary to check whether the vehicle certificate is consistent with the nameplate information inside the vehicle, such as engine number, frame number, factory year, exhaust volume, model, etc.

In addition, if you add an optional package or configuration, you must obtain a certificate from the 4S store to avoid unnecessary trouble in the warranty of adding the configuration in the future.
