2008 BMW 5 Series 535i 4dr Sedan (3.0L 6cyl Turbo 6M)
Extremely fun to drive. Great acceleration and handling. Sports package is a must just for seats - you can configure them the way you want (I feel more comfortable in it, than in $1000+ office chair). The iPod connector is great (even for ~$400). I use it every day, forgot about radio and CD existence. Bluetooth easy to use and very good. Nav controlled by iDrive is the only dark spot in this review, I consider this feature serious mis-design - it's not usable period.
Navigation - if you put in there features of $200 magellan or tomtom I'll be happy. Just don't do this last century voice recognition quality, non-functional search for POI with weirdest categories possible, and spelling with iDrive - are you kidding me? One more :make iDrive display crispy, not dim.
