WOW.  In a word-AMAZING.  
 Purchased the 2010 BMW 500i GT in February.  6,600 miles to date.  Truly the most comfortable, fun to drive BMW I've owned. The Sport Package is a must as it adds Adjustable suspension. Comfort mode is great for long highway cruising.  Sport mode is perfect for in-town stop light heroes.  The GT is a perfect blend of sports car and pack mule.  More than enough room in the back to haul luggage or bikes.  Rear passengers are treated to an amazing amount of room and comfort.  The Comfort Seats up front are probably the most comfortable auto seats on the market. Gas mileage in the highway has been 25 mpg on two 1,000 trips from FL to TN. Around town, stop and go has been 16 mpg.
