The coupes do not have greater value, for the most part, than the roadsters, unless it happens to be a twincam. Parts are readily available for these cars, but as another has already warned, look out for RUST. Aftermarket body panels to replace rusty units are, for the most part, crap (ask me how I know).
Here's a pic of my pretty severely modified '60A. Has an early B 3-main motor and B diff, so I can keep up on the highway.
