Following 3 7-series BMWs (2 740s and a 745) I find this 545 to be a much more enjoyable car to drive. With Sport Package, road feel and handling are both outstanding, although I am not a fan of the Active Steering. The interior is at least as comfortable as the 7-series and acceleration is superior. Plenty of room for 4 large adults, icluding sufficient leg room in rear, but 5 adults should only ride for short distances.
Again, with the Sport Package, the handling and road feel are outstanding. More than enough power for acceleration from standing or when accelerating from 70 MPH to 90 MPH.
Give me an option to the iDrive, please. Even after a 745, I still object to having to go through such machinations to change radio channels.
