I just got an 07 Ranger, and the Compass seats aren't nearly as comfortable, especially the headrests. My Ranger has WAY more comfortable seats, ten times the back support.
Aside from that, the only other complaint I can think of off-hand is the off-the-line grunt. But I guess that's to be expected from a 4 cylinder with CVT... once you're up to even 10mph it moves fine. It's just the 0 to 10 mph that seems a bit sluggish.
