Hey Jasonmrenda,
Just thought I'd put my 2 cents in. I did what you're trying to do. I traded a $6 -7k bike for a '68 GTO(a real 242, 4spd). It was completely driveable. Everything worked except the radio/horn. Here's what I got. It had a non-matching motor, '73 455 that was rebuilt a year prior, bored .030 and has a mild cam, have doc verifying it(motor still runs very strong, doesn't burn oil). Knew about it b/4 purchase. Was told the rest of the drivetrain was '68. Found out later the tranny was a '69 and the rearend was a'71. No biggy since the motor was non-matching. Just wished the guy was straight up. Trust no-one. If you find a car that is said to be all matching verify it yourself. It was funny, the guy checked the numbers on my bike even tho it was only 3 months old(Honda Shadow 750). Back to the car. It was painted 3 months prior to purchase. Not show quality. Has some orange peel, a 5 - 10 footer. Still has the same paint which is 5 years old. Here's what I thought it needed right away and did or had done: Rebuilt tranny, new tires, new shocks, springs, balljoints, swaybar end links/bushings. Rest of front end was already replaced, tierod ends, etc... It had new carpet. Bench seat was good except for some dry rot on back of passenger seat. Back of rear seat needed to be replaced. Door panels, headliner were good.
Have since replaced seats. Trunk, floor panels were good. Anyway, hope some of this information will help with your search. There's a lot of cars out there for sale. Be patient. Given the bad economy, good cars may be sold at lower prices and you may be suprised how many may be willing to trade for a bike. Good Luck!!!!!!!!!!!!!!
