I've only had this beast for 2 months but it's perhaps the best ride I've ever owned. I got rid of my Volvo S80 in favor of the Armada...and the difference is astounding. The ride in my Armada is soooo much smoother, I was surprised. The room in the back seat is PHENOMENAL! The raw power at any speed over 15mph is a fun kick in the rear. I've had it over 90 a couple of times and have never noticed the before mentioned "shake" in the steering wheel. I'm not looking forward to replacing the tires when the day comes either.
Power, room, ride, automatic low tire pressure alarm, ease of seating configuration changes, back up warning alarm, captains chairs. The way it cruises down the highway!
