Ok. My 1970 Challenger convertible cost me $550 after talking the guy down from $1875, in 1983. It was worse than this in rust and such, was missing the original engine (340), and crawled sideways down the road (had been hit, hence the fibreglass fender flares on the rear, dang). On year 4 of the resurrection, I saw a better than I had re-frankenstiened 1970 Challenger in a Pic-a-part, in Sunvalley California, up on yard stands. Very disheartening that day.
Then finally, I finished to the best of my ability, my Challenger Convertible. I had 5 years of sweat in that, a whole new body except the power budge two scoop hood (which needed extensive rebuilding anyway), new floors, new interior except the back seat panels and the steering wheel, new engine, rebuilt trans, added 3:23 posi, lots and lots of paint and bodywork...
All total, it was a solo work except hanging-welding on the parts-car back fenders. $4500 of my minimum wage earned money had gone it that that thing. I sold it for $5800. Only $1300 profit over five years of much toil and strain.
I'm sure it's been re-restored at least once since then, with fresh coats of factory Plum Crazy w/white interior, and that makes me happy, I saved it from squished.
After I get a home, garage, tools... and find and resurrect a 1961 DeSoto 2dr, I'd take this on...
