I have a '01 4.4 Sport and a '95 540 6 speed. The X5 is a very comfortably tight good handling vehicle. It runs very well and the looks are unbeatable. An awsome SAV no doubt. A great daily driver. But when you want that fuzzy feeling you get when you slam that ///M thru a corner just grabbin gears and smilling ear to ear... well.. go drive an X. You decide. I won't soon sell the 540!!!!
