A hypothetical (as of 2010) M-version of a hypothetical (") BMW car (the 4-series). This vehicle would be the high-performance version of the 'baby 6' coupe. However, because the existence of coupe versions of the 3-series, it is highly unlikely that a 4-series--let alone an M-version within the 4-series range--will emerge in the near to medium-term.
Suzzy: That was a sweet BMW M4 I just saw passing by.
Dr. Night: Really Suzzy? That's amazing, considering such a car does not yet exist. You dumbfuck.
