The Nissan Z Proto was unveiled this week in Japan and fans from all over the world could chime in and ask questions as the Japanese automaker unveiled the next chapter in the legendary Z car story. However, it was the annual ZCon gathering in the U.S., the largest Nissan Z gathering in the world that was featured extensively during the launch, and that's not surprising given the Z's main market is America. What's surprising, though, is that the two-door sports car won't be available for sale in Europe.
