going offtopic for a second: if you scroll to the bottom of the page on that article, you will see a link to an article on the new Lexus GS, you guys should check it out, it gave me some more insight into where they got their design cueues from, I already believed that the new GS's overall shape had a stark resemblence to the latest Nissan Maxima, but seeing that article quite clearly shows some other designs Lexus shamelessly ripped off.
Give it a check, the GS used to be one of bimmers rivals back in the day!
