There is something really different about the new Z-4, but I can’t quit put my finger on it. It looks the same, but different. What would be nice is to see a comparison of the first generation Z-4 along side the current 2009 Z-4. I know that there are many styling differneces but they must be subtle. The change from the Z-3 to the Z-4 was so obvious. I guess the biggest change is the convertible hardtop and for sure the larger twin turbo 300 hp powerplant. I guess the best thing would be to go to a dealer and see them side by side. Then take the new one for a spin. YAH!!! 300 hp in that little car must be a thrill.
