It is possible to "calculate" to characteristic signs. Buying in the market the second-hand car, especially by proxy, it is easy to catch the car with interrupted numbers. Recommendations of experts will help to be saved from such trouble.
The theory. If you have decided to get a second-hand foreign car and have chosen concrete model try to collect in advance about it an information maximum. Is better to make it, having examined similar model in salon which trades in new cars. First of all find out, where there should be identification number (VIN). At the car can be additional ViN-ovskie labels (are carried out as transfers), – learn, where they take places.
Practice. So, you start survey of the chosen car. It should be begun with check of a condition of a paint and varnish covering about identification numbers. It should not on colour and the invoice to differ from a covering on an inside of a luggage carrier, a cowl, a motor compartment. A soft surface (there is a deformation trace even from a nail), begin to flow paints and non-uniformity of its drawing – all it testifies that the place where there is identification number, was recoloured. And the repaint hides either failure consequences, or traces of change of number. The covering near number is possible потереть a tampon moistened with solvent: if the paint is dissolved at least partially, it is a sure sign of that it "not native".
Now it is direct about numbers and identification tablets. If number is interrupted, there are characteristic signs of this operation: the metal surface is deformed, slightly convex or bent more often. At a handicraft way of thrashing the double contour is swept often up; signs are not on one straight line, and "jump", at them various depth of cave-in; between letters or figures – intervals of different size. Especial attention turn on identical signs. They should not differ from each other the form or in the sizes. One more important point: if on identical signs in numbers you have noticed any prominent feature – be assured that these signs not the factory. Firm number is put by a uniform stamp, "handicraftsman" for each figure or the letter uses a separate brand and repeats characteristic "error".
It is more difficult to reveal "the criminal" car when number is replaced together in a detail or that its part on which it is beaten out. As a rule, in this case number – factory. Therefore it is necessary to examine places of fastening of this detail to a body. Simple way of detection of such replacement can be простукивание. You should guard, if a sound at простукивании deaf, "wooden" or jingling. It is necessary to remember that in cars separate parts of a body fasten a method of contact welding. Junctions usually represent points in diameter of 5-6 mm. If in places of fastening of a "number" detail to a body there are traces of other kind of welding, and their surface also are deformed – means, the detail is fixed on a body not in the factory way.
At survey of the engine pay attention to a platform with number: it should be equal, and signs on it are beaten out accurately and brightly, without double contours. By the way, the platform is pierced on the milling machine tool from which there are traces in a kind полукружий. They are well visible even at strong corrosion.
The described signs simply enough to reveal even to the nonprofessional. There are also others, but they can be revealed only experts. To them also it is necessary to address, if you still had doubts.
