We just bought a 2006 X5. Looked at others in this class. One of the most important reasons we decided on the BMW was the missing 3rd row seat. They are virtually inaccesible in the other SUVs we looked at. I know people want this 3rd. seat, but be realistic, they are worthless for humans older than 6. If BMW had this seat, we would have gotten an Audi A6.
