CHATTGUY 
2009 BMW X5 Diesel xDrive35d 4dr SUV AWD (3.0L 6cyl Turbodiesel 6A)
2009 X5 35D
 Diesel mpg averages 28-30 at 60-70mph, in town I am getting about 22 mpg. I was worried about the iDrive, but it works great once you understand it. The voice navigation is best I have used. Power tailgate sounds flimsy, but works. Power is awesome from the 3.0 diesel, frugal yet powerful. I was concerned about ride with runflats, but so far just seems a little stiff.
