I bought the Armada shortly after I got rid of my Excursion and I have to say I am very pleased. The truck very comfortable and the features are great. I haven't had any problems and would recommend this truck as worth the price.
I was surprised on how quick the Armada is. It has no problems getting out of its way with a full load.
I would the mpg were a little too low but you have to remember you are buying a V-8 not a hybrid. I would like to see more rear cargo room but hey...not ever truck can be an Excursion.
