Congrats on the new ride. A year ago I looked at a new 2009 550i with the M sport package and MT. Nice car! I really enjoyed driving it and even with the 19" the ride wasn't too harsh. Nice handling sedan with a smooth great sounding n/a V8. It seemed perfect for me.
I didn't buy it because the safety ratings on the E60 is abysmal. And the side impact is the lowest of all mid-sized sedans in the class. It's really unfortunate.
It stopped me from getting one, but I'm hoping they learned and the new F10 will be much better rated. Except the downside (for me) is that they won't be offering it in a n/a V8 anymore. I want the old motor and the new body.
