OP - looks like you've got your answer. 11,000 miles on my '09, and I too love it. I'm in Wisconsin and no dead battery, no tough cold starts, no issues with my urea reservoir (which had it's scheduled 10K fill last month) and I'm also getting about 22 MPG with city driving using winter blends (was getting 28-29 last fall with "normal" diesel). I loved my previous 330 ZHP and miss it but don't regret the trade - this X5 is a definite step up. Great cruiser, luxurious, can haul a boat and kids, TONS of torque and power, and still sporty enough that I have no qualms throwing it hard through the turns. Plus you'd get the new iDrive...

P.S. - order it for pick up at the Performance Center in SC like me and others here and you'll REALLY see what an X5d can do...
