2006 BMW Z4 Convertible 3.0i 2dr Convertible (3.0L 6cyl 6M)
From a Z-3 To a Z-4
 Well i went from a z-3 to a z-4 miss the curves and the shark gills on the side, but love the power cornering one touch roof and better sound system then the z3.Cup holders in a great spot,not in way of stick shift. Larger trunk,can fit golf clubs and small cooler in this one. They also put a glass window in this one instead of the ole plastic one. Great lighting one the front light up the road also. Owned a 2003 Boxster also at one time and this is less of a money out of pocket kind of car also.
