Is there such a thing? I have just searched for an hour and really cant find any solid info google or on these forums. Maybe I'm not the the search master but I have tried b4 asking here.

Can anyone say if it was an option and what was changed on the x5 M version? Was it just some badges and interior options?

Here is a link to an ad, is it a scam?
Cars for Sale: 2005 BMW X5 4.8is in West L.A., CA 90025: Sport Utility Details - 286273590 - AutoTrader.com

There is also an imola red 2006 at the same dealer with m badges.
