A lot of replies to this thread are referring to the old Colorado/canyons, they are totally new for 2015. I test drove a 4x4 and they are smooth and quiet. Sticker mpg is 20-24 and felt like it had enough power. Not sure I'm wanting car payments again and they are pricey, for the V6 Z71 it went from 30,000 to 37,000.
