I am needing some information on the 2011 GMC Terrain we own a 2008 GMC Sierra right now and we are wanting something with better gas mileage and we are looking to trade the truck in on a Terrain and I was wondering if its a good suv to buy and if the 4cyl or v-6 is better and is the gas mileage much different between them I have a 2 years old baby and I want something safe so any help would be great thanks!!!
