here are several 350Z videos and some track time against some other cars doing a road race vs. circle track in Japan. See video link "350 vs. other cars"
The drivers are biased as they have a 350Z, Boxster, S200, and M3 all going at it for 4 laps and the 350Z is kicking the a$$ out of the M3. IMO....NFW!!!! A 350Z can out run a M3 on a road race. They also got some nice video of a GTR.
