I grew-up in Europe where everything is Diesel. So, we bought our car and chose European Delivery. We put a little over 2000 miles in 12 days. The engine response was great, very quick of the line, but if you are not in Sport Mode it plateau's around 3500 RPM, which is common for Diesel. I wish BMW will offer V8d on X5 as well as 5 and 7 series. (I will purchase tomorrow). The car turned heads everywhere, something that my wife didn't like very much :). One more thing, the car is very capable and very adaptable to many lifestyle. I will say is a commuter or run around town car. Hope this helps.
