I was checking out a listing for a car on craigslist, I called the guy and asked him to provide the VIN but he refused to provide it to me because he thinks that I'm going to duplicate it. He said that I'm the first person to ever ask him for the VIN of his car he is selling and that "he's just a little guy". I tried to explain to him that on autotrader.com people always provide the VIN for the car and it's perfectly fine to give it out but the guy refused to provide it nonetheless. So, is this guy being paranoid and stupid or is he a liar who is pretending like the car has a clean title but in reality does not. He said he'll give out the VIN if I give him my Social security number.
