While I don't use the SAV nomenclature, I can see the logic, as the X5 is missing a lot of "Utility" as compared to most SUVs, e.g., my 2005 Focus Wagon has more cargo space than my 2010 X5, even though the X5 weights more than 5,000 lbs, and was much more of an off-road vehicle (ground clearance, protection plates under the vehicle, etc.). The X5, IMHO, does fall somewhere between a "real" SUV and a car... it seems to have a lot less "utility" than my prior 1992 Ford Explorer, but it does handle a lot better and is more fun to drive.
