 This is my 17th car, following just about everything but Audi (Porsche 928 and 996 Turbo, SL500, BMW 735, and assorted Ford and Chevy cars). Hands down, this is the best automotive execution I have driven. I'm a nut for picking apart failed user interfaces (my job), and this car has not disappointed me, however I'm only about 75% familiar with it after 400 miles. MMI is a bit complicated, so the Driver Information System and steering wheel controls are fabulous; you can do 90% of what you need very quickly, intuitively, and with eyes forward. IPod integration, including playlist support, is great, and will save lives. The motor and drivetrain is wonderful.
