Now obviously I prefer the X5, since I drive one, but the MDX is not the minivan some of these posters are making it out to be. It came out first in this Car and Driver comparison, linked below. Granted, it's from 2007, but the model is still basically the same. It was one of the factors that led my wife and I toward our 2008 MDX.

BMW X5 vs. Acura MDX, Cadillac SRX, M-B ML350, Lexus GX470, Volvo XC90, VW Touareg, Land Rover LR3 - Comparison Tests
