I saw a new 350z on 280S cruising @ 75mph. It was blue with paper plates from an SF dealer (forget which). My initial impression was that it looked like an audi tt had sex with a new age celica. It looks much better in pictures than in person. I was not impressed and prefer the looks of the wrx. The wrx is kinda cute in an original, ugly duckling kind of way; I felt the z was too much of a mish mash of designs from other makers and didn't exude "Nissan" like other nissan cars. The classic Z element has been overlooked IMO.
BTW i read on one of the nissan boards (freshalloy probably) that one of nismo's first us projects will be a 50 hp upgrade for their vq series 3.5l v6 (specifically the new z). Theories are that it'll be done with a supercharger (evidence is the supercharger on nissan's '03 trucks) and/or chip, i/e. Just a rumor though, but that will make the new z one nice ride and have output similar to the e46 m3.
