Screaming Fast
 I have owned 2 Acura TL's, and Infiniti G35 and several other lower model Acura's and even a 1987 325.  This car is a blast to drive.  Super fast.  You can take a corner as fast as you want and the traction control will prevent you from ever losing control.  Tried that in a G35 and the car spun out.  I've had some issues with battery drain and dealer said battery was fine.  After reading many posts I decided to get BMW battery tender.  Very easy to use and BMW didn't engineer the car to properly maintain battery charge if you are opening closing doors, trunk etc without driving it. Knock on wood.  haven't had trouble.  I do notice trans lag when car is cold but is fine after a few minutes.
