on an alpine white, I personally love black accents - fender grills, front grill and trunk spoiler. I have an OEM trunk spoiler in my garage that i never installed as i went with aftermarket CF on mine. go on the BMW accessories site and look for it. It looks like it fits right onto the back of the trunk, not on top, very understated but sporty but you're going to want it to match the body color, it won't look good painted black
