 I have had the car for about a month now and absolutly love it.  It is a powerful machine.  Almost too powerful to have in an automatic.  The sound system is great and the navigation is easy to use.  The only real problem is the brakes.  They squeak.  Usually, when you spend good money on a luxary car the brakes don't squaek.  Not with this one.  All in all who cars about the brake noise when the car is super fun to drive.
