I have a 1965 Series 1 E-Type coupe, and it's with a heavy heart I'm considering letting it go to a good home. I've been researching, but have been unsuccessful in determining an honest fair-market value for it. Can anyone offer some insight?

The specs:
It currently has a Ford 289 with Offenhauser heads/manifold, 650 cfm Holly carb, and c4 auto tranny. The body is straight, but with some rust on the undercarriage. A new set of floor panels are ready to be put in. The glass headlight covers are perfect, but is missing the rear window glass. Though it's been sitting awhile, there's no reason it won't fire up with a little tlc. The new owner will probably want to do a full resto job, but it still looks pretty enough to garner respect and admiration from the neighbors. For what it's worth, it has a very interesting provenance/history.

I appreciate any information anyone can provide.

Thank you,
Mike
