I'm thinking of picking it up, tearing it down, and if it's in decent wear on the rotors and such rebuilding it, otherwise just screwing with it, would it be a bad price, or likely to be unrebuildable without spending an excessive amount on parts? Is it a bad price?

 

For reference its about 100 miles away, but I don't think any junkyards near me have any rx7's to pull one from, so I don't think that's a huge deal

 

I guess it depends how badly rusted it might be inside. Given the distance, maybe see if he is willing to shine a light into the exhaust ports and get some pics of the inside to check for rust.
