Long time lurker...first time poster. I am desperately waiting for the twin-turbo diesel. I am currently in Germany and torn between a good deal on a stock 3.0 or waiting for the price list for the 35d. I have the benefit of using the military car sales channel here and we should be getting the diesels here by the end of Feb/early March. I, like everyone else am interested to see if the packages differ than the 3.0si. I haven't driven the diesel over here yet but of the X5s I do see, they are mostly diesels (Euro versions that is).
