Black leather with brushed aluminum trim -- carbon leather was too much black and I didn't think wood belonged in an M3, at least not one with clearly sporty exterior and interior colors. And as others have said, Extended Leather with black just isn't worth it because the quality of leather they use on the transmission tunnel and underside of the dash feels like plastic.
I also got the non-Competition 19" rims (preferred the look compared to the other 2 options and liked that they were forged). I like my combo because blue contrasts well with black, red, silver, and orange, which just so happen to be all of the colors on the exterior and interior of the car.
