 Just purchased the 535i xDrive and absolutely love it.  It handles curves like no other sedan in its class. Really have to pay attention to my speed because of smooth ride. Fuel economy isn't bad for 300 horses and vehicle weight - currently getting 25 to 27 highway, but still in break-in period. Very comfortable interior with lots of room.  Could use a little more storage, but not a major issue - the golf clubs fit fine!  I do agree that the cup holders are ridiculous.
