Mate, one US car mag got 0-100 in 4.1. And a modded M5 will be better again. Yes there is a big difference in price, but because you have a F6 or a Ford you keep trying to make it all better by saying that the f6 is equal! And my brother has had many Ms and bimmers. Not teh best car or his fav car. Just the car that his wife will allow. 250k car allowance isn't too bad.
