In the second-hand car market, I believe that many people will have such a question in the mind when purchasing, “Is this car a bubble car?â€. We all know that swill trucks have certain hazards. Even if relevant regulations require that used cars for sale should be clearly stated whether or not they are slop wagons, many owners or brokers have intentionally concealed this fact. So how do we identify whether the car has soaked in water? Recommend the following methods for identification. First, observe the entire vehicle. Judging from the appearance of the vehicle, whether the tire is covered by blisters, whether the vehicle's bracket is rusted or not, whether there is water vapor in the vehicle's lamp, and whether there is mud in the vehicle's bumper bracket. Whether the entire vehicle has obvious signs of being modified. Vehicles that have been soaked in water generally have a different feeling: They look as bright as new cars, but there are obviously traces that have been used for years. Second, identify with internal details. Cars that have been immersed in water will undergo some processing. Although we can't see any difference between it and ordinary cars on the large surface, we can still find differences through some details. For example, if the bracket of the seat is covered with blisters, there will be traces of rust. Unless all of them are replaced with new ones, they will leave traces of rust. This is different from the corrosion that has been used for many years, and the entire frame is rusted. The situation, but there are some places that can be seen not to use too long. In addition, if the seat cushion is also blistered, there will be a musty smell. If it is washed, then the taste will still be left behind. If you just listen carefully, you can still find it. There will also be some details in the car to see the vehicle passing through the blisters, such as traces of water seepage on the edge of the window, or inflexible switches. Third, experience the function of the vehicle through driving. The test drive is the most effective way to experience the condition of the vehicle. From starting to accelerating, to driving, to speeding down the operation, braking, stopping, etc., we can look at the situation of the vehicle's power system and experience it. The stability of the vehicle. In short, it is best to experience it several times in the test drive, so that you can accurately determine whether the vehicle is a bubble truck.
