I just bought a 2009 35d. It replaces a 1996 Yukon that has about 160k on it. The Yukon drives like a log wagon compared to the X5. It gets about 16mpg. It hauls everything and has been a good workhorse, but for not much more $$$$ than a new Yukon the 35d really is an amazing step up. We lost some cargo space, but are getting about 24mpg and bmw road handling. The x5 is a really nice. Also this diesel has plenty of acceleration.
