I'm in a similar spot as the OP...I recently purchased what was sold to me as a 24,000 original mile '73 out of Colorado. I finally pciked up the car last weekend and while it isn't exactly as offered, it is 100% solid from any structural issues, never hit, 90% original paint, etc. Little issues which could have been huge are things like a missing castle nut and cotter pin off a tie rod, what the heck! Any way it runs very well...but now that it is in the Pacific Northwest my number one goal is to drop the sub frames, pull the transmission and fuel tank then strip all the sound deadener. This car has never been undercoatted so that's a plus. While the suspension is out we will clean up and powder coat all these parts, replacing all the bushings and properly seal the under carriage with whatever the best solution the body shop can offer, if that is por - 15 or what, I don't know given there is no rust to start with, then reinstall the suspension and running gear. I figure this will run me around $5k once I'm through all the "while you are in there" items. I know a car is only original once so I'm trying to avoid my impulse to stip the body and go crazy with paint...there is some surface rust to deal with but it is very light and certainly not through any panels but it drives me crazy so I have to deal with that, at least. So to echo what others have stated, if you are not doing the "shot gun" approach with an open limit on your VISA card then you might want to go the direction I'm headed towards getting the car running right, strip the suspension, etc and go from there.
