I can't tell if those are the same model years. But this site:
2005 Nissan 350Z 35th Anniversary Edition Price, Specs & More | RSportsCars.com
Has the 2005 35th anniversary edition, weighing in at the following
Weight lb (kg): 3225 (1464)
2005 Nissan 350Z | Nissan : this one has 1474 kgs.
Your JDM site claims weights of 1480. So...wait, USDM was lighter??
