I considered getting the range rover sport here in Dubai. There are a lot of them on the roads right now. The local guys love any new model and go crazy to get them first. I have the full size range rover and it's a much bigger and slower than the sport but a lot more usefull with a family. If you want a fast mid size 4x4 get the porsche cayenne turbo, I've have had one for over a year now and still smile every time I drive it. No other 4x4 can compare to the speed of this thing it's awesome.
