Simple. Isn't the X5 the "kewlest" SUV in the world?!
When we first got it, there was hardly any X5s in town. It was "kewl" that everyone would come up to our X5 and check it out. I remember one time, there was a guy who came up and asked about our car. After checking it out, he stated that he was going straight to the BMW dealership to order one!
To this day, I still think we have the "Kewlest" SUV in the world....Thus, Kewl X5!!
