Only red interior cars (in both the 3000GT and Stealth), had charcoal headliners/visors, etc. All other interior colors of both cars had beige headliners/visors.
We vinyl dyed the interior panels in our satin black 3000GT. Have to clean the panels (aka, scrub) with a wax/grease remover, then spray them down with this bulldog stuff (helps adhere the paint/dye better), then lay the vinyl paint/dye. Comes out VERY well. But... it's all in the prep work, how long/well it will hold up.
