what to do if you have the "lost" car

Sort of same story. I built a 70 Duster drag car from scratch when I was 17. 340, HEMI 4 speed, Dana 60., In 1974. Got married, had a son, went through a couple jobs. 4 years later sold Duster, no time or extra money to race. Son turned 16, i wanted it for his first race car, tracked down car 1 mile from my mother in laws house, sitting in a crappy garage just as I sold it, to the same guy, a roller with a title. Well, my son and I stopped in to make an offer. I sold it for 2500. The guy had an attitude, but I wanted it back. I offered 10,000 cash. He basically laughed in my face. Guess what? It's still sitting there. So, no matter the price, sometimes it doesn't matter. Good luck with your situation.
