I pulled up to my local gas station and sitting there was a black wagon with quad exhuast dropped and had bmw M wheels.... i had never seen the wheels before but they had the M sticker on it.... car just had an X on it for a badge..... has anyone seen anything like this?? or know of a car it could have been.... this thing was sexy as hell.... any ideas??

X5 4.4/4.6/4.8is?

some people have taken 540it and put the m5 quad exhaust on them... you would end up losing your spare tire (hence why m5s dont have spares)
