Stick with the Chevy....
Much nicer to play with, after working on a ford I always feel frustrated, Chevy's are much more fun...
If it has no rust, mechanically is great, and you really like it, then what price feels about tight for you? If I wanted one (I did a few years ago, but got over it) I would think about $1,500 if no rust, running and stopping. A complete brake rebuild if done right could cost 500 and up for just parts.
