Gold =
1980's called, they want your ideas back.
lol j/k!!
It's really up to you, what you want gold can be changed into gold.
IMO it will look very tacky and for the better part won't suit an E-Body at all.
Cadillac or Pontiac...definitely, E-Body?? - nope.
Still, it's your choice........
You could keep the dash black, door panels black dye/paint the console gold and get gold seat covers in suede.
Might go together with white carpet to break it up a little....I really have no idea.
