There was a Carbon Black Metallic car at the big gathering in Munich, the one with the chrome rims and red/white plate.
Though my eye picked up on it''s slightly inky bluer blackness the camera doesn't show the difference at all in the dull cloudy light. I suspect it's deep metal flake luster would really sparkle in the bright sunlight, as I know that color from a friends M3 here, and it is glorious in bright sunlight, though the all black interior rather wastes the potential of the Individual Division's magic.
J?rgen has said that the Carbon Black Metallic with full Saddle interior is one of the prettiest color combos he has seen so far, but sadly that car is in deep storage and has never been to a Z8 Club event.
