I disagree with the prior reviewer. I too came out of an Audio A6 3.2 into a 550i sport, but think the BMW is a better car in every respect. I have had no problems with my car after almost 2 years of daily use, hard use. I drive this car hard and it delivers! The engine is something to be reckoned with, from 0 to over 100 there is power to spare, just punch it and hang on. The interior is solid as a rock... no squeaks or rattles almost 20k miles. Where the A6 is plastic this car is leather, a true luxury sports sedan. (my A6, my 2nd , was in the shop many times)
Yes, the cupholders are small BUT anyone driving a car this nice should not be drinking anything that could mess it up! I'm irritated by this feature too but it definitely discourages me from carrying liquids in my beautiful car.
