I Offset 
2009 BMW X5 Diesel xDrive35d 4dr SUV AWD (3.0L 6cyl Turbodiesel 6A)
Even better than I first thought
 A brief update on my initial (3/1/09) review of my X5 diesel:  Now at 5,025 total miles.  Average mpg now 21.1 -  even though average speed is only 28.5 mph (most of my driving is urban, much of that on the very hilly streets of San Francisco).  Most impressive of all - not one single thing has needed repair or even minor adjusting.  This is a first for me. Over the years I've been fortunate to have only had brand new cars,  never used. One VW, one Lexus, five Mercedes, two Range Rovers, and one Toyota. Loved them all in one way or another, but all had needed overnight stays in the shop at least twice or more at this point in their lives.  A BMW, made in SC, tops them all - amazing.
