 After two Corvettes, I decided I needed something more practical but still fun to drive.  The Infiniti G37X was a little too small and too stiff and the 328xi a little too expensive.  The A4 was just right.  It handles well and accelerates nicely with the turbo 4.  I don't think the V6 adds much more.  It holds 4 people comfortably.  I wouldn't go for 5 unless 3 are very small.  The trunk is huge.  The interior is handsome and the sound system is fine.  This is my first experience with BlueTooth and its much better than OnStar.
