I had an '06 CC Colorado that was a rattle box and traded it in. The build quality seems to have improved and the truck now has a more solid feel. There still is a little too much plastic on the inside, but overall this is a fun truck to drive. I can't speak to the reliability until I've had it awhile. Steering is crisp and responsive. Braking could be a little better. The interior cosmetic changes are nice too.
3.7l I5 is peppy enough for me and I can park it anywhere with ease. No longer have to park at the rear of the parking lot. Fuel economy is good too. New 5 year 100k mile warranty is also a nice perk.
Seats are good, but could be more comfortable. They could use better grade materials for the a/c & heater console controls.
