seems to me z3 being the older car.. seems more of a enthusiasts car, and the z4 more refined obviously.. both great cars and would love to drive a z4 to see how it compares... my z3 is so small and compact being the narrow body, i dont know if i could live with a wide body z3, as nice as they are, or a Z4...
hope i dont offend any z4 owners by saying this... sorry..
