Having had a couple of Bimmers in Mineral Gray I'm a little biased but, the rich classy nature of that color is a nice change from the typical silver or black.
Carbon Black has a Very interesting nature with natural beauty but IMO, only when it's freshly washed/polished. An hour or two later, when dusty :<) ... not quite so much.
I personally love black but I've moved beyond it since I'm no longer willing to wash my cars so often.
Really, either way could be a Great choice for you.
