Google has knocked BMW off its pedestal, by zeroing their page ranking. The reason for this was their violations against the Google Webmaster Quality Guidelines, specifically the first point about "cloaking."
I’m not very fond of Google right now, but I don’t mind seeing them be the means of karmic payback to BMW. They act like the rules for the rest of us don’t apply to them, and they encourage their customers to think the same way. It’s kind of satisfying to see someone call them to account for their behavior.
