I love my X5 4.4. I drove the MDX when it first came out and was impressed with the power, and the space. I didn't consider the X5 because I didn't want to spend that much money. I always thought it was the best looking SUV (SAV) on the road, so I finally decided to drive it. Once I did, I was hooked. X5 wins hands down!!!
