On the Sport models that I test drove, there was a button labelled "SPORT" just to the rear of the shifter. Is it there in your pics, but we just can't see it?

I ordered sport as well, and am really curious to see how it feels on a daily basis. My current E53 did not have sport. On my short test drive, I really didn't feel the big difference with the button on or off, but I'm hoping that overall the ride will be better than the non-sport.
