Gentlemen, gentlemen, please. Does it really matter, if one version reaches 60 mph, in the blink of an eye faster, than the other, or one goes around hair-pin corners more safely at a slightly slower speed. What are you going to do with all those thousandths of seconds you have saved? All that matters to me is getting from A to B with style, comfort and safety, to arrive hassle free in my 9000 CSE 2.3 turbo, that starts, runs well within itself, and STOPS.
