I bought my Colorado brand new, and have had nothing but trouble with it. It's died on me twice, I continue to have problems with the cd player. The AC squeals like a stuck pig, plastic molding had warped, carpeting comes up in chunks of fuzz. I've had problems with the ignition switch, airbag sensor, cruise control light, and interior paneling. The interior is of very cheap material and reeks of poor design. It's a sharp looking truck, and when it's not in the shop it drives and handles ok. Unless you're a die hard Chevy fan, I'd advise you to look elsewhere for a truck. Based on my experience with this, I'll never buy another Chevy truck.
The exterior is quite sharp looking. It does turn heads.
What can I say, reading the other reviews, my experience seems to be atypical, but they (Chevy) need to spend a little more time on quality control.
