When I was in high school, everyone wanted black interior in their Mustang, Maverick or Comet. I have seen some pretty crappy conversions to black interior. Some use regular spray paint without proper prep work. I'd leave it white if it looks good. I agree with Dennis, $2,800 on the bottom end. Some guy offered me $5,000 for mine at a car show this past Sat. I tried not to chuckle since I think that he was pretty serious. He said that he had sold his '71 GT for $800 back in '88. Seth
