Depends on what you plan om doing. I have a 2009 GMC Sierr@ and average 16mpg around town and 21-22 on a trip. Not bad for a V8 and a comfortable ride. I also have a 2011 GMC Terrain, nice car, all wheel drive and handled realy nice this winter. It has a V-6 and averages about 22-23 on the highway. If I could only have one I would pick the Terrain, best of both. Of course of you do not need 4WD that changes things a mite.
