Marci,
NOTHING wrong with the white interior... I have had mine since 1994 ( the white interior that is), and its only needed to be cleaned once (mine is a convertible and had NO top at all until about 2002).
Although I would ONLY do white if its using factory type vinyl. Any cloth will likely get dirty quicker...
The white vinyl feels cooler that black vinyl seats. Its alot more unique than "black"...
Although mine is a 66, you could still get some ideas. I used the factory/repro "white" seat covers and door panels and painted the console white too. But, I chose to use Bright Blue carpet and paint the dash with the same bright blue paint that I sprayed on the outside of the car, blue dash pad, etc... Still looks "stock" but in a color combo never offered from the factory...
I think for sure the floor and dash is black, but what about the doors?
Not 100% sure, but door panels should be white, while the door tops (painted areas) should be black...
Too bad I moved or you could have looked at mine (I used to live in Redding/Palo Cedro and for a short time in Castella). Where at in Shasta county?
