ken, congrats on your purchase!

if you arent a fan of the red interior, there are mods you can do to make it more bearable. there are some photos floating around of a VX that had its red door panels painted black with some red accents that looked great! and it would reduce the amount of red in the interior. other than that persistance will be the only hope for changing out your entire interior.

as far as the cupholder, if it fits a standard din slot, it should work in the VX. you may need to trim the lower bezel a very minor amount.. problem is that the VX din slots are not friendly for that style cup holder. the top din slot has the overhang directly above it, and dash angles back slightly to the lower din slot so all you can really fit in that style cupholder is a can or small cup. search for "trooper cupholder" for an isuzu factory cupholder that mounts to the back of your center console
