I traded an '04 Silverado 2500HD for this Colorado. Although the trim /options package is a 3LT, it falls way short of the Siverado 3LT package with far fewer bells and whistles. The truck is fairly comfortable with a stiff chassis. The engine has plenty of power and pickup and at highway speed is pretty smooth. At idle there is some vibration. I have had a few problems with rattles inside the cab. When bringing it to the dealers attention the tech merely tied up the HVAC cables. This seemed to correct the rattles for a short while but they are back and worse at this writing. I haven't had the truck through a winter yet. We'll see!
Sliding sunroof. Good stance with the 235/75/15 tire option.
Could use improvments in the area of engine idle, a little too much vibration. A little more attention to detail in the area of cab rattles
