Late to the party...
I passed on Frozen Grey and went with Alpine White, black rims and black trim package. The interior is Magma Red (looks more orange to me). It's too bad they don't offer Mineral White or that would have been an easy choice over Alpine White. I think Alpine White maybe needs a high gloss to look good though since it's not a metallic color to begin with.
Still waiting for delivery, maybe late this week or next. Mine is an M40i with all options. It's still winter here of course, but the roads are mostly free of snow, water or dirt. I'm going to be real tempted to take it out for a spin.
FYI, I really did like frozen grey, but couldn't get past conditions of owning the color.
