Congrats on the new car, and welcome to the board! 
I too have a 330 (330i) on order and am currenly driving a 2000 Mustang GT. You are exactly right about the Mustang. It is really fun to drive, but I can even hear myself think while doing 70 on the Interstate. My Mustang is immaculate and flawless mechanically, but I sure will be glad to get rid of it.TranceLvr said:Gosh, I didn't even think of the break in period. Guess I will just have to drive it a lot in the beginning.
This will be my first BMW; I never would have thought I would own one. I am currently driving a 2000 Mustang GT. While I know I will miss the raw power of that car, I know I won't miss the squeaks and rattles. The worst part is they are even louder and more annoying now.
