Sorry. Try http://www.nissannews.com/index.html and then click on the first topic (Nissan North America Reports May Sales).
Then scroll down...


So far in 2003 (Jan 1st to May 31st) there have been 14,317 G35 Sedans and 10,761 G35 Coupes sold.

 

If the June 2nd Hiroshima article is correct I would assume that the entire North American production will be completed prior to the Australian production startup later this month. That's great news for both the US and Canada - now if I can only get a delivery date!
