We did, or rather re-did a resto on a 69 Charger at work. I was the project supervisor for that one. Everything Ian said about the B bodies being cheap junk is actually rather gracious, and even a bit charitable. This one had been "restored" by a previous owner who had owned it for perhaps 20 years. It sat in his garage untouched for most of that time because his wife wouldn't let him spend any money on it. She passed away, and since they had no children to leave an estate to, he threw a huge amount of money into the car but did the work himself.
Subframe connectors, a reman 440 with first generation Holley Projection FI setup, all of the toys. Electric exhaust cutout, Gear Vendors overdrive, a full boogie 727 "Race" Torqueflight, the works. The guy painted the shell himself and did all the bodywork and wiring. The downside was that he apparently was not (ahem) skilled or qualified to do these things himself, and the car simply didn't work. To make matters even worse, from what I've been told he developed cancer partway through his project, and rushed to complete it. I believe he did live long enough to drive it in a limited fashion before passing. His estate was left to a friendly neighbor who sold everything off.
Our client bought the car for a song at an auction, and brought it to us to sort out. He spent somewhere around $20,000.00 on it with bodywork, rewiring, and engine work (stay away from the early Pro-jection). We were able to make the car run and drive, start and stop, be safe, and look good doing it, but is about another ten grand from perfection. The original body work was really that bad, and the guys budget didn't allow him to consider a rotisserie job. However the car is a beast to drive, and quite a workout to drive in traffic. It wants to run like the race car it is, and nothing else. 'Tis a beast, and the guys ready to sell it and buy something more pleasurable to drive. There is a potential problem with that, he has followed similar era Chargers on Barrett-Jackson, and wants a Barrett-Jackson price for it, and the car just won't carry that kind of money. I think it's going to his son on the West Coast where money seems to be a lot cheaper & looser to be sold.
