that the current 5 series is too big? i am coming from a 1995 325is, followed by an audi a4 avant. i am getting a 530 xit. i have wanted a bigger car for awhile, primarily for comfort of others. do mostly city driving. i am a bit concerned about the car feeling unweildy. i of course am hoping i adjust easily. i know the current 5 is larger in almost every way that its predeccesor. anyone moved from the 5 back down to a 3?
