At first glance it appears that the price of the M Sport package on a 535i has been reduced from $6,500 in 2011 to $4,800 for the 2012 models. The BAD news is that M Sport no longer includes either Active Roll Stabilization (ARS) or Adaptive Drive. There's a new option in 2012 for Active Roll Stabilization that costs $2,500. I can't determine if this also includes Adaptive Drive, but it doesn't say anywhere in the press release that it does. Thus, while at first blush it appears that the cost of the M Sport package has gone down from $6,500 to $4,800, it actually has INCREASED from $6,500 to $7,300, and this may not even include Adaptive Drive. This is on top of a base price increase for the 535i of $2,150 (from $50,100 to $52,250).
