2005 BMW 5 Series Sedan 545i 4dr Sedan (4.4L 8cyl 6M)
From 7-series to 545
 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.
