Do South Americans actually identify themselves with being "South American"? If you ask a Brazilian their nationality do they say South American or American?

How should Mexicans refer to themselves? "Mexico, officially known as the United Mexican States (Spanish: Estados Unidos Mexicanos)" http://en.wikipedia.org/wiki/Mexico So calling us the United States could be equally confusing.

The fact remains that America is the defining part of our name.

Sorry, this started off being a serious question about identity and I got carried away.

They don't make much money on the parts. They kill you will the labor.
