I'm not knocking the NA. It's a great high-performance car. I drove one for 3 years and thought it compared well with my C4 Vette and certainly wouldn't mind owning another one. 
the audi spoiler is a fraction of the size of a crossfire. Just because it has a Chrysler emblem doesn't mean it was meant for America. I know for a fact there are a lot of crossfires in Germany and Europe. They can keep up with any Audi or Porsche on the road.
