Loving It
 Great car!  Powerful, fast and fun, yet refined.  I can sum up driving this car in one word:  confidence!  This is a car for persons who love to drive and to feel the car interact with the road (as opposed to being shielded from it).  The iDrive is fine (even helpful) once you get the hang of it.  Try it, you'll like it.
