I am just about to paint mine dark metallic blue and I will probably do a standard dark grey/light grey scheme that you find in most cars today. Anything from the windows and up will be light grey and anything below will be dark grey. Probably try and get rid of the old "wood grain" and maybe put some brushed sheet alloy in instead or if not just use silver.
What i do want to know is what the hell to put on the inside of my rear pillar. See cutsGotBoost's picture, I can't quite see what the material the inside of the rear pillar is made of. Mine had the stocko Brown/White interior which is quite ugly, and it had BROWN carpet on the inside of the pillar. Looked pretty crap and I think I will try and cover it with some stiff foam and vinyl, or I may even try and fibreglass in some panels that will cover it.
