This is an excellent SUV, however with all SUV's there is the drawback of horrible gas mileage. Although the Envoy isn't the worst in its class in terms of gas mileage, it doesn't impress in town. Highway gas mileage on the other hand, is quite bearable. My tank holds about 20 to 22 gallons, and I usually get about 350 miles to the tank on the highway.
There are 4 or 5 AC outlets in the vehicle which allow for various things to be plugged in on a cross country trip! The ride in the Envoy is very comfortable and smooth.
Gas mileage. With today's gas prices, the deciding factor on the purchase of a new vehicle is gas mileage.
