Why does GM sell 3 times as many full sized SUVs as the rest of the market combined?

I think it is just market perception in the large SUV market. GM has had a lock on the luxury and blacked out "FBI" look/market. The Expedition is a good vehicle with excellent luxury packages but when you think luxury most likely you will hear Escalade or Denali as the must have vehicles.
