Not sure about readily available colors, but why not do it yourself?
After taking care of some surface rust on the floors in my Midget 1500, I thought that with floors all nice and happy, it was time to tackle the carpets and vinyl panels, all of which had seen better days, especially the carpets.
I resurfaced all the vinyl panels with a kind of hard, thin felt that I found in the 100 yen ($1) store! Much better looking than the vinyl and easily cleanable. Cheap to boot.
The carpets I made myself as well.
Took the pieces for around the gear shifter down to the local shoe-repair shop for stitching.
Perfect fit, much better than original.
Making it yourself gets you the color you want (black/dark grey in my case) and a fit and finish factory made carpets/panels can never hope to attain, unless they're for a Bentley or some such.
Just take your time, measure twice and cut once and you'll get exactly what you want, plus the satisfaction of having done it yourself. /ubbthreads/images/graemlins/hammer.gif
Tailor made versus store bought...
