I know a guy who bought a 1972 Road Runner from a guy because it had the same options as the car he bought brand new. This one had a 383 with dual carbs and high rise sticking out of the hood. He bought it and after a few months found some things that seemed odd to him. He dug through his old paperwork and it was his original car.
Something happened to me like that. Bought a 1972 Plymouth satellite. Sold it. Bought it 2 years later. sold it. Bought it back 5 years later. Sold it again and found it in a wrecking yard years after that.
Glad to hear he got his old car back. I bet the stories he could tell about the car will be soo cool to hear!
