theft

yesterday I got a knock on my door from my neighbour telling me the police was looking at my car, so I ran out to make sore everything was okay. I had to show them everything I had for the car and then they asked me for the key and arrested me. It turned out after 9hours in a police cell the car had been sold to me stolen. So i now have to try and claim the money back for it. It just shows you can get ripped off by anyone i bought it from a dealer not a guy down at the pub. So pissed off with it all
