I've flip-flopped - 2 years ago, I picked the Z4 over the Cayman. Now, I have to say Id get a 2009 Cayman S over the new Z4. They've fixed what I didn;t like about the Cayman (under-powered and no LSD), and taken the edge off the Z4. Moot point, though - plan on keeping my Z4MC.

 

these look great in person, especially the dark blue. i hope there is an M version in the mix

 

best z ever. amazing look.
