It's spent its whole life in AK - previous owner bought new from dealer in Anchorage. 4.8L is a beast. It's loaded - we have yet to encounter an option it does not have. LOVE the heated seats and especially the heated steering wheel. Rear seats are heated as well. We are Bimmer people, though somehow the wife ended up with a Mazda SUV prior to the X5 - zero comparison. We run studs in the winter though likely unnecessary - however winter tires a must when it's -20 deg F (standard all weather tires are hockey pucks at that temp). We did away with the height adj air suspension though - started with sensor failures, then one of the fronts went - it's all conventional struts/springs now. Gas is expensive here (think CA prices) but wife's commute is short, so no biggee. Bit of a love/hate for me - love the performance, but taking care of it is a b*tch.
