How to check the car when buying for an accident, accident

Buying a used car is a much more rational investment compared to buying a new car. Leaving the dealership gate, a brand new car immediately becomes cheaper by at least 10%. At the same time, the more expensive the car - the faster it loses in price in the first years of its life. Of course, premium brands are cheaper, of course.


Therefore, it is not surprising that a person who wants to buy a good, quality car not only considers the offers of car dealerships, but also turns his attention to the used car market.


However, most of us are far from automotive subjects and little is understood in technology. Therefore, most of the buyers follow the new car to the car dealership.


More “savvy” motorists know that competent diagnostics at a service station before buying makes it possible to avoid problems with a used car with a guarantee close to 100%. Even more literate car owners,which can be attributed to “advanced users”, they themselves are able to check the technical condition of the car during the inspection and determinewhether the car was in an accident or other accidentbecause "they know where to look." These two categories of citizens constitute the backbone of buyers of used cars and they do not know how to check whether the car was in an accident or not.


Those who do not understand cars at all, but did not accumulate the desired brand for the new car, resort to the help of “advanced” friends and relatives who they take with them for inspection of the options chosen from the ads. Unfortunately, not everyone has such friends, and those who are are often busy and cannot stop watching cars at a convenient time for you.


How to check the car before buying for accidents, accidents and whether it was "broken"?



Recently, autonomists have had an alternative to take with them a friend who understands something in cars. The name of this alternative is the thickness gauge of paint and varnish coatings. This compact meter measures the thickness of the paint that the part is painted on. It works like this: you lean the sensor against the bodywork of the machine - and the screen shows the value of the thickness of the paint applied to the machine.


When the car is painted at the factoryFor most models, this thickness ranges from 80 to 150 microns (1 micron is one thousandth of a millimeter). When the item is repainted after the accident in service - a layer of paint is more than 200 microns. That is, the difference is almost twice! This is due to the fact that at the factory and in the service station uses a slightly different technology of applying paint.

If under a layer of paint there are embedded body defects, then the distance from the sensor to the metal can be much more - and 500, and 700, and even more than 1000 microns (this means that the putty is a thick layer - more than 1 millimeter).


If, after painting, abrasive polishing was done several times or the part was painted without compliance with the technology (that is, no primer was placed under the paint), the deviation will be in the opposite direction, and the paint will lie in a layer of 50-60 microns thick. The latter means that the paint will begin to fly off about a year after the work and the part will be covered with numerous chips. That, too, as you understand, is not very good.


So, the thickness gauge immediately shows these deviations from the norm. And everything that (possibly) the seller tried to hide from you immediately becomes obvious.The buyer, armed with a thickness gauge, is free from the danger of buying a battered car: the human eye may not notice the trick, but you can't fool the device!


Initial inspection of the car- This is the moment when it is necessary to check the body, and everything else you’ll check in the service station. And here the thickness gauge turns out to be an indispensable assistant! Checking the body with it takes 3-4 minutes, you can not fool the device. And even if you do not understand anything at all in machines, you will not confuse the difference in the readings of paint thickness on the device screen!


There are many models of thickness gauges on the market today, but most of them are cheap and not very accurate products. A good device now costs 5,000-6,000 rubles. But if you live in a large city - there is no longer a need to buy a thickness gauge. There are companies that are ready to rent this device for a week for an amount that is several times cheaper than its market value.


What else to check before buying a car?



Of course, the body is not the only thing worth checking in the purchased car. However, this is the main factor on the basis of which one can already decide for oneself whether it is worthwhile to drive this car into service for technical diagnostics or it is better to go and see another option.


In principle, there is nothing to worry about if the car has painted parts that in appearance are no different from unpainted ones. You can use the painted parts identified during the inspection as an argument for bargaining with the seller, but you should not give up the car for reasons of principle if it has 2-3 painted elements in different places. This is unreasonable.


At the same time, it is very important to protect yourself from a car that has been restored after a serious accident, in which the body geometry has suffered. The broken body structure is like a fractured spine. On such a car, for example, it is impossible to adjust the angles of the wheels. Or the windshield may crack a month after the next replacement for no apparent reason. Even a quality repair can not restore the original characteristics of the machine with a damaged geometry. In the event of a new accident, the previously deformed power elements of the body will no longer effectively absorb the impact energy, which will affect safety. In most cases, these machines do not live long. If you still buy such a car, then when you want to change it - you will be tormented to sell, since there will be few people willing.


It is from such a machine that the thickness gauge will save you: a car that has been in a serious accident will have a lot of repainted parts lying side by side.


If, at the initial inspection, the device did not reveal any signs of serious body accidents, then such a machine can already be considered as an option to purchase and to coordinate with the seller the presales diagnostics of the technical part. Now you know betterhow to check the car for an accident, accident, paintingand save yourself from the "broken" cars.
