Sorry for bringing back a really old thread, I never had a 350z...it never appealed to me like the 370 did, but I did notice that you guys missed something else.
Other than the digital speedo, individual tpms, and better looking side view mirrors....I really liked the slope of the dash, it was a lot more sloped, a little like the 300zx or NSX. The 370z dash, although better overall, misses that Lamborghini feel dash-wise. Also, the door handles on the 350 were aluminum...ours are plastic
