Hello, I bought a used car a week ago, everything was fine. I went through the VIN code, which is located on the windshield and, of course, agreed to it in the technician, there was no problem anywhere. After a week, I found out that each window on the car has a different sanded VIN code on the windows, plus it occurs to me that the VIN on the muffler is overcooked and it also occurs to me that some VINs in the engine part are completely missing. I don't know if he didn't have it smeared on the registration check so that it would pass and he shook me .... advise
