I had one stolen. I got it back 36 hours later, fully detailed, washed, waxed, inside clean as a whistle, tires oiled, etc.... Unfortunately, there were $214 worth of library books that had been in the trunk waiting to be taken back to the library the next day. That and my expensive winter jacket, the expensive power pack and a few other things were missing, too, which the insurance wouldn't pay for. Obviously, it was going to a buyer immediately.
The worst part of the whole event was having to convince the police and the insurance company that I didn't give it away, sell it for drugs, arrange to have it stolen, etc. The fact that it was fully paid off and I would have gotten a hell of a lot more money selling it than the insurance company would have paid me for it didn't impress anyone. I was questioned over and over again until I lost my cool with the insurance company and yelled at them. One cop came in and said rather snidely, "Are you sure _________ doesn't have it?" "I said no, I'm positive he doesn't have it." "Why are you positive?" "Because he's been dead for three years!" (My late husband's name was still on the title. We had just bought it before he died and there wasn't any compelling reason to take his name off as I could have sold it with only my signature and it would cost $35 to take his name off.)
They were able to get a fingerprint off a CD that had been left in the player and a year later, the 15-year-old kid stole another car and got caught. I went to his first hearing just to see what he looked like so I could shoot him if I saw him in the neighborhood again (just kidding, just kidding) and his mother was wearing what looked suspiciously like my jacket.
