Met a Previous Owner of My '65 Today!

I have never run into any previous owners of the cars I've owned but did get a 69 valiant back twice.... the first guy that bought it never finished paying for it and he just brought it back. The second time I sold it, that guy sold it to somebody else and a year later broke down and he left it on the side of the road. I saw it on the side of the road going to work one morning so I called the guy that I sold it to and the title was in my name still. He told me to just pick it up because the other guy didn't want it anymore and he gave me the title back. I've had bad pennies come back to me before but this one was a good one. The only bad penny I had was a 71 VW super beetle but there was nothin super about it...
