That's strange, the official production numbers list from Isuzu indicates all the protons had the black and gray interior.I have seen several protons with the Red/Black interior. I rather like the look.
Gosh, I would think if I had all the colors of the rainbow available to re-paint the VX, I would pick something more exotic than the same proton yellow that was on 479 other VehiCROSSes.
Hey, but that's just me!
Good Luck!
