Value of 1967 Ford Mustang Convertible

Hi all, my mother has a red, 1967 Ford Mustang Convertible and we were wondering how much it would be worth if we were going to sell it. Here are the details: It got a complete teardown and repaint 2 years ago, and has been in a garage with a cover ever since. The paint is better than when it came out of the factory. It has a 6 cylinder "200" motor, with what I believe is a 4 speed automatic transmission. In addition to the paint, the top was also replaced. The car runs great, starting it used to be a hassle, but a new carburetor fixed that. The only slight problem with it is the interior. The dash is slightly warped and the sun visors could use some re-stitching. The seats have had sheep-skins over them since I was a little boy, to this day I have no idea what they look like, but my mother says they are in good condition. Anyway, I would love it if any of you could give me a rough estimate, as we are very curious. I tried looking online, but I failed to find a sight that either would go back to 1967, and or do it for free.

Thank You
