I know I have seen at least 2 other G37s here on my campus (Bentley University). One of my friends has a OB one, I have a PG one, and I have seen a red one before too. I also saw someone driving a GT-R the other day through Bentley. That thing is rediculous.

I have seen some around though. Not common, but you see them throughout the Boston area once in a while.
