On second thought if you took the highest prices of all of them:
BMW X5-$68,837
Lexus GX-$45,500
VW Touareg-Couldnt find a price on that one
Acura MDX-$45,045
Lincoln Aviator-$45,865
GMC Envoy-$34,902
The best and most expensive Escalade you can buy is the Escalade ESV which cost $52,391
All these according to edmunds.com
Like I said,pricy or not,its a luxury SUV and should be up there.
