This is impossible to start to answer without much more detail and pictures etc. I've seen cars that would match your project description change hands for anything from $2K to $20k and "restored" from $15 to $50. All depends on originality, quality, completeness, uniqueness etc.

Good news is that you already know you are buying it for "an amazing price" so what's to question?. Just do it. If you do however, I would not go in thinking ou can snap it up as a bargain, do a quick "restoration" and sell it on as a profit (which your line of questioning seems to imply - correct me if Im wrong). Porsche economics just doesn't seem to favor "flipping". Parts are too rare and expensive, Seemingly simple repairs often end up more complicated and contingencies too unpredictable. Well that's my view anyway.

As an example, after having been through tis twice with a 70 and a 69, just 'cause you can't see the rust doesn't mean it's not there. Rust in the pan means you know it has started and only once you have it completely apart and stripped will you know where it stops.

Good luck.
