 I haven't enjoyed driving so much since I was 16.  This car handles like a dream, quick acceleration with power to spare, transmission is very smooth, breaking is well-balanced, corners like it's on rails.  Love the iDrive, I would never have gotten it if I could have found a car with premium sound and no Nav but it really makes a difference.  iPod and Bluetooth interface is awesome. BMW should be marketing this as iDrive with Nav instead of a nav system. After 2000 miles I've been getting a combined 20+ mpg which would be better if I wasn't having so much fun with Sport Drive.  Looked at Audi and Infiniti but nothing handled like the BMW, I'm hooked.
