Pit,
Yeah, the old muscle cars were a lot of fun, and in the late '70's/early '80's they were pretty affordable, especially the Mopars. We got fairly lucky with our 6 pack Cuda in that mopars had finally started to increase in value by the time we sold ours. For what ever reason, they did not start getting pricey until a couple of years after the Fords and GM's had started to take off (except Hemi's, they were always pretty high).
I've got a sob story to rival your Gullwing tale! My partner, the guy with the $$$, found a Ferrari 2 seater convertable for sale in San Antonio, this was probably around '79. I don't have any idea what model it was, but it was an early '60's car with a 60 degree V12 with six weber carbs. A guy had embarked on a total restoration, he rebuilt and detailed the motor and trans, and completely disassembled, piece painted, and reassembled the chassis/body. From all appearances he did a superb job... that v12 was beautiful, the detailing was top notch. What was the trouble you ask? Well, when the guy picked up the rolling chassis from the body shop - he had just had a couple dozen coats of hand rubbed Ferarri red lacquer applied (this was the '70's, and they still used lacquer on high end exotic car restorations), he was unloading the car from his trailer when it got away from him and smacked a pole in his shop dead center on the nose. The nose was screwed up pretty good, (Aluminum body) it was certianly reparable though, the hood was not on the car, so the nose was the only thing messed up. His paint job was esentially hosed though, he would have had to repair the nose, and repaint at least the whole front of the car. Well, he got disgusted, put the car in storage, and just never could work up enough enthusiasm to get back on the project. My buddy was foaming at the mouth, and digging for his checkbook, the guy wanted $16K. I pulled him off to the side, and told him we need to think about this one a little. I knew that I was going to have to do esentially all the wrenching on the car, and I also had an idea about what Ferarri parts would cost. The car looked complete, and from the quality of work the guy had done thus far, I'll bet the running gear was jam up, and all the bits and pieces necessary to finish the car were probably there, just like the guy promised, but I was just not willing to gamble $16K on it. If the motor had turned out to be junk, it would probably have cost us another 16 to repair it, and what if a lot of stuff was missing? A hand full of parts could amount to serious $$$ on a Ferarri.
I had mixed emotions, and my buddy was about to cry, but I talked him out of it. He has never let me forget it, he remembered the year model and so forth, and it turned out to be one of the cars the yuppy Wall Street types were paying 7 figures for back in the late '80's when the rich and famous started pulling their money out of the market, and investing in exotic cars. No matter how much we would have ended up spending to finish up the restoration, we could have made a mint! I guess you live and learn. I did manage to keep one fairly valuable car from my muscle car days though, a '69 Boss 429 Mustang. Just wish I still had the '66 Chevelle, and 6 pack Cuda to go with it!
