Small world! I just got my 2014 sDrive28i with M Sport, 19's, in Le Mans blue, and also ride a BMW bike (S1000RR). Living in SoCal AWD isn't really for me, plus I got the car because it reminded of the E46 wagon which was a favorite of mine back in the day in terms of size and dynamics.
I Love this thing, there aren't many rear-drive compact cars available these days with 50/50 wt distribution, 260 torques, and 19 inch 255 tires in the back from the factory. It should also look pretty cool towing the bike to the track for track days (BMW car towing a BMW bike!).
My previous car was a E46 M3 that I got new in 2005. Added H&R coil overs and aftermarket wheels.
