I don't have to buy a car. The following is the relevant information: 1, precautions for buying a car: be wary of various offers. Everyone wants to get a bigger discount when buying a car. If the sales really meet your requirements, the price of buying a car is much lower than originally expected. Cheer up at this time, because the store can't operate at a loss, and it will definitely make more profits in other aspects. Online platforms can also bargain for buying a car. For example, buying a car with a low down payment is a preferential price. Only when you have the target model will you go to the 4s shop for a test drive. There is no goal to come to the 4s shop, just a headless fly touching the 4s shop. The salesperson will recommend the most expensive car in the store. Therefore, you must have a target model before you go to 4s stores or 4s stores and online platforms to understand the intended models and model parameters, and then come back and think. Pay attention to the contract details. When buying a car, whether in a 4s shop or online platform, once the contract formalities to be signed are involved, we should pay attention to the details. Don't sign everything, or sign without reading the contract. Doing so can't protect our own interests, and may even cause great losses afterwards. 2. Details in car inspection: Visually inspect the paint surface of the car body and check whether there are scratches, spots, dents and wear on the paint. Observe whether the car paint has color difference in sufficient sunlight. Open the door, push it from several angles, let the light shine from different angles, and check whether the metal sheet is flat and whether there are repair marks. Check the vehicle nameplate. The vehicle nameplate is located on the driver's door side or in the engine compartment. Pay attention to whether the factory date is too long apart. Generally speaking, if the time is more than half a year, the car is likely to be a stock car or a test drive. Open the hood and check whether the engine compartment is clean. If the vehicle is left for a long time or used, there will be obvious dust or stains in some places. In addition, check whether the engine oil is sufficient and whether other oil levels are qualified. Check the basic functions of the vehicle, such as whether the window rises and falls normally, whether the air conditioner is cooled, whether the air outlet smells, whether the function of the center console is normal, whether the wiper works normally, whether the lights are lit normally, whether the sunroof is opened and closed normally, etc.
