America VS. Everyone else

I would like to know good things and bad things about American cars and Foreign cars. I own a chevelle right now and its been a good car but im am moving off to college and am going to buy a smaller car. I like american muscle and I like imports but my friends all like imports and dont get me wrong I like imports also I mean thats what Im going to buy, but which one is really better. (not a very specific question)
