Think of it this way though...LOTS of these cars have been raced, wrecked, rebuilt et al.
It could still be a decent middle level car.
Oh, and I have a corvette story for you....one of the local VW TDI guys takes his 5 speed Jetta into the local VW dealership, I think it was in dayton or cincy or something. They have an old corvette on the back lot, four mis-matched mag wheels, covered in dust, but it runs, it's a new gasser jetta trade in, of all things. Convertible top is kinda shot...but the guy's TDI VW is getting up in miles. The guy offeres the vee dub in trade and they accpet in a second. Guy drives the 66 home, it's an ugly shade of puke orange or something....
Finds out from the tank sticker and the paperwork still in the glove box that it's an original blue 66 425 HP Big block 4 speed ragtop. Guy also had a 66 Chevelle SS 396, Gold with a black vynal top...with 21,000 original miles...so once complete and back to big block status, the Chevelle had a garage mate.
But the guy is a hot rodder at heart, and couldn't stand not cutting up something he owned. So he wold both cars to collectors, and now runs a 48 chevrolet Street rod, one of the ones with the "fastback" styling, really a neat street rod....
I love Corvettes. There is also a mid sixties ragtop sitting in a barn about 4 miles from me, everey once ina while the doors are open to that barn, and she is still sitting there. That Blue big block 75 ragtop is still sitting out down in asheville....if you can live with rubber bumpers....and if you can convince that guy to sell...
