Yep, you're missing out on all sorts of good things that we get here in Oz: 40d in X6, 40d and 30d in X5, 30d and 20d in X3, and 23d and 20d in X1. You can get diesels in 1, 3, 5 and 7 Series vehicles. Eight years ago BMW didn't sell any diesels in Australia (the E53 3.0d was the first in 2003) and now it sells more diesels than petrol models across its entire fleet, and in X models it's something like 80 percent diesel.
