A body parts availability
I absolutely agree with all the above. FMJ parts are harder to find but not impossible. E's and B's can be expensive. Like sometimes crazy expensive. C's can be had cheap in very good shape if you want a land yacht, and they are oh-so-cool. I've seen plenty of really nice turn-key C's for less than 5K. With the A's the early stuff is sorta hit and miss for parts. 67+ are a lot easier.
If you're determined to have a "correct" car the price tag goes WAY up. If you're like me, I drive them and don't get too excited if I scab something off another car for mine. As long as it works decent and looks OK I'm a happy camper.
Rust is your enemy. Missing parts aren't much better. The small stuff adds up quickly and can get you upside down in a hurry. Ask me how I know! :BangHead: I have 17K in parts ready to go on a 2K car that will never be worth anything near what I'll have in it. But it will be done the way I want and I intend to drive it till I drop.
Before you buy something, it's not a bad idea to shoot your thoughts out for specific feedback from the group. One of my cars is a one-year-only, and I bought an entire matching parts car just so I could have a junkyard in my back yard.
