Z4....excellent choice. I think that's the only thing good to come from Chris Bangle's tour at BMW. Everything else is pretty gay. The new 6 series might not be too bad (only seen photos...not in person), but the new 7 is out there, and the new 5 series looks like a friggin' Pontiac Grand Am, less the fact that they're adding a 500hp V-10 to the M5.
The Z4 is better than the Z3 in sooooo many ways. Just wait until they finally put the ///M engine in that puppy
It'll be like this:
New ///M Roadster
& [insert all other cars here]
