The VW 'eg TDI would be my choice, IMHO it is, or used to be with the four-corner suspension, more capable in rough terrain than a BMW Xx which are primarily designed to conquer potholes and curbs, and maybe a roadkill or two thrown in.
Edit: Well, it looks like only the Porsche Cayenne Turbo is available with the air suspension now, and it isnt available in the US with a diesel (though I read somewhere that Porsche is putting out a diesel Cayenne soon, prob not coming across the pond). So I am not so sure about the eg's rough terrain capability any more.
