Unless....
Unless you're going to really strip the body of all the trim, wiring, interior, etc., I'd suggest that the drastic change you suggest will show, one place or several others, and LOOK LIKE SHIT.
I'm okay with Inka, though never owned a bimmer in that color. I just think that unless you'll go all the way, the spots you "miss" or choose not to paint will look really bad. Think: Inka against some kind of blue?! No thanks.
