Dream Car under $50K
 I traded my Z3 in for this car and what a diffence.  I love everything about this car.  Everything that I felt could have been improved on the Z3 was greatly improved.  The power band is smooth thoughtout the range.  Handling is remarkable, it drives thru curves as if on rails.  It has a sporty ride but is still not uncorfortable on long trips.
