In general I would say that I love the car. It handles great in curves and high speeds. I agreed with the other people saying that if BMW keeps doing cars like this, they'll have a customer for life here.
Engine sound. The reaction of everyone when they know you bought a BMW. The looks. Acceleration. The lights below the door handles are great!
Cup holders. The in-dash cup holders are simply wrongly placed. The one inside the center console is impractical because you need to keep the lid open to use it. The gas mileage is good but since the car needs premium fuel, it could be expensive. The XM radio should be standard.
