Maybe growing up and buying/driving my '71 Challenger in Las Vegas impacted my opinions; as much as I love black cars, and am ok with black interiors, its the recipe for a blast furnace in Las Vegas summers. Even with A/C.
And I think the H6XW black and white interior (white seats, door and quarter panels, headliner, black dash, kick panels, carpet, rear deck) is an awesome combo for most exterior colors (mine was GF3 originally but painted white by its previous owner and the interior worked for both of them).
Its your car, do what makes you happy. Mine is staying H6XW inside, and 98% certain white on the outside with bodyside black insert moldings that most get rid of.
