heheh.. Finally took the dive and took a Z4 for a test drive. I was wasting time while my buddy has his 325Xi serviced. I do have to ask why are these guy's salamander's. (sales staff)
As far as being nimble.. heh... let just say they didn't improve it. Though I do like the silky sound of the I-6. Something my Miata is missing.
However, my fun factor rates it at 5. Needs to shead a few hundred pounds. Top works really nice..and the interior. Well, if you like weird and funky its cool.
