I'd recommend as Step #1: go look at various cars in your area to get an idea of what's ahead. And take an experienced "classic car" guy along. Also - don't take money on that first trip!
Step #2: post photos here of cars that pique your interest. You'll get lots of detailed feedback on the good, bad, and ugly.
Step #3: be very aware of rust issues. Rust/corrosion can be visible (body, floorpan, etc.), and invisible (inside body parts). And the seller's description of "Rust Free!" usually just means there's no extra charge for the rust.
Buying a car sight unseen can lead to more problems than you'd ever expect. See it (or have a trusted friend see it) before making any agreements. It's way too easy to find cars these days - the 'net is a great help. The "urge to own" emotion usually overwhelms the "can I handle the work" brain cells. But especially if you're just starting out, there should be a personal inspection and test drive.
