Just took delivery of my new 2006 BMW 530i Automatic. What a difference from the 05 model I had. It's quick, handles better, and the premium sound system is unbelievable. A great improvement in horsepower and fuel economy over the 05. Didn't notice any major changes over the 05 except for power and performance.
Sound System (premium), I-Drive seems easier, great ride, truly a magnificent vehicle.
