iDrive, stereo, 3D maps, shiny this, whistling that.
Seriously, in my opinion if that's what you're buying this car for, then you're wasting your money. There are only 2 important changes, in my book. 1 is the engine upgrade, but hey, do I really need another 50 HP? Probably not.
The other is the lack of a left pedal from now on. That's the more important change for me. And in the end, all it means to me for sure is that I 100% absolutely, positively will not be getting another 6 series when the time comes. At the rate sticks are dying, I'm going to have to buy a 2013 Subaru SBZ in a few years...
