M4 badge is 100% official, no MSRP, just blind deposits being left for what will inevitably be one of the best M cars ever. I am a super huge fan of the F30. I've lived with two 320i's now for two months and have driving every example of F30 available. Leaps ahead of the e90, and very reminiscent dynamically to the e36. Tossable, controllable, light on it's feet etc, etc.
