With the current domestic market new car sales continue to improve, the second-hand car market has also ushered in a new development opportunity, how to find a more cost-effective second-hand car has become a hot spot. Today’s selection of second-hand cars brings you a BMW 730Li (labeled 740Li) that left the factory in 2014, only driving more than 40,000 kilometers, because it is still under warranty, so this type of car is generally a boutique second-hand car, just when I thought that the whole car only had simple spray paint and other small problems, a trace was still found by me.
● Exterior car paint inspection – paint thickness meter is not necessarily reliable?
It has to be said that the repair process of the accident car is changing day by day, which will make many second-hand car appraisers look away. Many repair shops in the maintenance, in order to achieve false real or even use paint thickness tester detection, if the thickness of the car paint is high, will use polishing and many other means to make the thickness of the car paint reach the normal range.
● Check the condition of the car still rely on eyes and hands!
When inspecting a used car, you cannot blindly rely on tools, the most accurate method is still eyes and hands. Touch it by hand to check whether the flatness, smoothness and thickness of the paint surface are uniform, and whether there are rough surfaces, sand marks, noise, etc. With the eyes, you should observe whether there are color differences, flaws and other problems from multiple angles in the sun.
After careful inspection, it was found that the right side of the car was painted as a whole, there was no obvious sheet metal part, and the most important thing was that the frame part was also painted, it is worth mentioning that the frame painting often had a serious collision.
● It is simple and important to remove the sealing strip
Removing the seal inspection is a very simple job, many netizens in the comments have said that when choosing a used car, the car dealer will refuse the buyer’s request to remove the seal, in fact, it is just a pretense that many car dealers feel that you have no intention of buying. If you identify a car, most sellers will agree to the buyer’s request to remove the seal for further inspection, unless the car has been involved in a major accident.
Through careful investigation, we agreed that there had been a serious impact on the right side of the car, but fortunately it did not hurt important parts such as the engine. Through the imprint of welding and gluing, it is judged that the roof, A pillar and B pillar have been replaced, which is already a more serious accident car. The reason why it is judged that the roof and other parts are replaced rather than repaired is to consider that there is almost no sheet metal in the entire frame, and the frame of the BMW 7 Series is an aluminum body, and the sheet metal is difficult and can only be directly cut and replaced.
A few days after the inspection of the 7 Series, I coincidentally learned that the car was repaired in a repair shop I knew well, and the photos before the accident confirmed my inference.
● Summary
Many netizens believe that inquiring the insurance record can easily understand the condition of the whole vehicle. In reality, in order to sell at a high price, some car owners would rather repair their cars at their own expense than leave evidence in their insurance records. In addition, if the repair of the vehicle is not responsible for the accident, it will also not be recorded in the insurance record.
As the repair process is getting better and better, the basic knowledge and experience requirements for buyers when buying used cars are getting higher and higher. Various loopholes have caused the opacity of the second-hand car market, as a buyer should learn more seriously second-hand car detection knowledge, we will gradually launch the interpretation of various models in the future, so stay tuned.
