I traded in a 2015 Colorado Z71 for my Ranger Lariat, and, in all honesty, the Colorado had a little smoother ride down the highway. Enough difference to bother me? No. They are both trucks so I expect them to ride like a truck. And, as I drive the Ranger more, I become more accustomed to the ride and don't really notice the difference. I find it has a nice and comfortable ride, so nothing to complain about. I'm not sure why a review found the interior to be small. It seems big enough from my perspective. I figure if you want a really smooth ride and a huge interior, then move up to a Lincoln Navigator and forget buying a truck.
