2006 BMW M5 Sedan 4dr Sedan (5.0L 10cyl 7AM)
Such a fun beast to be in
 Took delivery in Germany (ED program - look into it!) and received it back in the US one month later.  What a fabulous car.  Whether driving at sane speeds (50-80 mph) or Autobahn speeds (150+ mph) the car is very predictable and gives excellent feedback.  Doesn't feel like a 4000+ lb car through the twisties.  SMG is a great system, once you get used to it.
