I think an M7 would be a good idea, anything to beat the likes of the Mercedes S600 or S55 AMG; both which have over 500bhp.
On a previous 7 series model; (the one in production in late 80's and early 90's) an M7 was produced, it was more expensive than the Alpina variants, and was considered too expensive by BMW for what it was. It was only available in Germany; in VERY SHORT supply.
Oh and the 760 defiantly is coming out, already in Germany.
