 After in-depth comparisons to Mercedes ML 320 CDI, ML500, Lexus GX 470 and Cadillac Escalade, the BMW X5 won me over quickly in a variety of areas from build and finish to actual ride, drive and handling. Most of the others offered spongy-swaying rides, not the X5. The V8 is a beast and the 6 cylinder is more than adequate and the mileage is much better. Certain option packages are well worth the cost like the Premium package, the Technology package, Sport package and definitely the Active Steering as well as the Comfort Assist. The Active Steering provides an incredible increased handling effect. And 4 yrs/50k mile bumper to bumper INCLUDING maintenance is sweet as well.
