Not a big fan of the Colorado/Canyon myself. They seemed preoccupied with rakish angles on the sheetmetal, and how cheap they could make the plastic interior pieces look. I was looking at one to replace my '01 S-10 single cab, and walked away disappointed after the test drive. Within a couple of days, I decided to buy an extra extended warranty for the S-10. Looking back, it wasn't a bad idea, the 2.2L 5-speed is dual-fuel capable, and I just sent a job application to an ethanol plant here in Wisconsin. Could be a beautiful relationship!
Regarding the "GM products are to be avoided at all costs" zinger, I could very easily say the same of the Ford products I used to own and have since walked away from, including a fairly recent Explorer model. Bottom line, everybody in the automotive business builds a lemon or 1000. It's up to the consumer to find out if they won the prize.
