I cannot understand this comparison, the M5 is a great car, the F6 is also an awesome car but with a price difference of $160,000 you cannot have a fair comparison there is the never ending list of things you could do to the F6 with the spare 160,000 that would blow away the M5, but I bet if you gave me a F6 with the money difference between that and a Ferari Enzo I could get it close to that aswell... Both great cars, both differn't markets, but on a head on comparo the F6 kicks it's Butt, as has been mentioned before, a F6 with $15,000 spent on it would hose an M5 and you have alot of spare change over the M5. How about we get DallasQld to line up a Modded F6 that is in his state at willowbank or the middle of nowhere for all I care and see who wins, evan still if I had a F6 that stayed within 2-3 car lengths of an M5 I would feel like the winner knowing I had spent 150+ grand less
