New to the board but am a long-time owner of a 1972 Albert Blue Sun-roof coup. That said, the vehicle in question is currently under restoration. One of the last components needed to complete the project is new carpet. The vehicle is Albert Blue as mentioned earlier and originally came with tan leather interior. I intend to change the interior to black leather (seats, door panels, package-tray, etc) and will use the German high-end wool (versus domestic pile) as the material of choice for the carpet replacement. Note that the head-liner is currently black.

Questions:
Does changing the color of the interior lessen the value of the vehicle? The vehicle is not quite concourse quality but pretty close.
What carpet color options were available in 1972?
What carpet color options would be correct for this model year?
Where do you recommend that I purchase the new carpet set.
Anything else that I need to be aware of when I replace the carpet... Thanks in advance
