Vehicle Height Question
 

Does anyone know off the top of his/her head the overall height of the vehicle on the lowest standard suspension setting? Thanks in advance

Duuno what you mean by "lowest standard suspension setting"
but, from the Spec Sheet, 2006 X5, on the Front Page of X5World,
it sez:

Height, in. 67.5" for the 3.0 & 67.2" for the V8

lowest setting on the suspension w/o modification (what it comes with from the factory)
