SANTA MONICA, California — The new 2009 Nissan 370Z is scheduled to make its first public appearance at the 2008 Los Angeles Auto Show, November 21-30, 2008. But when a prototype of the new Z-car came to town in early October, we were fortunate to be invited by Nissan to take a look at it. No factory-authorized information is available yet, but we were allowed to look (as long as we didn't look too closely) and venture a few wild guesses.
