Ah, I knew I would get something on the 90% comment. The information gathered comes from Dun and Bradstreet, coupled with the "Buy American Act" which does not allow for any corporations to advertise their product as wholly American unless over 80% of the products used in the final product are designed/manufactured by American companies or by overseas companies owned by American corporations.
And I own an '07 America, which I am well aware is not manufactured solely in Britain, semantics.
