Just picked mine up last week, SMG truly is amazing. A whole new sort of driving experience. Together with the M3, it's really special. I did the Performance Center Delivery, so I got to drive an SMG M3 there prior to taking my own away. I can't say enough for the experience. It's a short driver's school and just a taste of the Car Control Clinic, but allows you to see and feel what the car can do and then baby your new one until it's broken in.
