Great info! Thanks for sharing. A couple of comments:
Your M dealership's service bays are so pristine, and the fact that you can view them working on your car is fantastic. If we had that type of setup here, I would never have to wonder whether the techs properly reinstalled the wheel lugs with a torque wrench rather than an air gun.
It's curious why we in the US don't have M-specific dealerships, given that we buy the largest proportion of the M division's output. Is it because BMWNA figures that the presence of M cars in the main BMW dealership attracts all buyers, including those for 328s and 528s, serving as an aspirational model?
Love the side-by-side pic of your M3 and new M5. The M3 looks petite in comparison. Makes me feel better about using my M3 for track duty--it's certainly not a 911 or a flyweight Exige, but in the grand scheme of things the M3 is a fairly reasonable size for the track.
