 Okay, granted I have only had this car for a few days, but I driving it back from Kentucky to Atlanta, I got to know it pretty well.  The car is unbelievable!  Extremely smooth, stable, quick, predictable, quiet (no squeaks or rattles even on bumpy roads), and most of all.. FUN!  I had one small problem with the door weather stripping that I knew about when I purchased it, but BMW fixed it under warranty, so now no problems.  I could never buy another vehicle than a BMW.  This car gets so many looks too, no matter where I am.  It's just a beautiful, awesome car.  I love it!
