My wife and I traded in our 2007 Armada SE for this 2009 model, and we haven't had a single regret. I never thought a full size SUV like our Armada would be this much fun to drive, but it is. Granted the gas mileage could be a little better, but hey its a small price to pay for all the safety & luxury features it provides. We looked real hard at the Ecalades, Tahoes, and Denalis when we decided that we needed a big SUV, and I can truly say that none these vehicles have anything on our Armada.
Roomy interior, Bose/Musicbox with subwoofer entertainment system, DVD, rear camera, power lift gate and third row seats.
Better gas mileage of course, adjustable time delay feature to turn off lights, and a delayed power off feature when engine is turned off.
