This site shows some views that each group supposedly shares on each the other group.
It has German Views on Americans, and American Veiws on Germans.
I have no official opinion on that, as I dont think I have ever visited the country of Germany, but either way, the site seemed to possibly be fairly interesting. The site does not in any way, reflect my own views on that.
