I have very few problems with this truck. I have the 4.3L which has plenty of power. Like every GM product I've owned, you can't beat the powertrain! I get about 22 to 24 on the highway, can't complain about that. (I'm no light foot). I have the sport pack, fatty tires, sport suspension, custom wheels, it still turns heads! The only complaints I have are: 3rd door handle-I've broken 3,not replacing it again! 3rd door/driver door rattle bad together...really bad! The CD player does whatever it wants to. It might play the disk or spit it out for no reason or just keep trying to read it and then spit it out. I still love the truck and would buy another...keep the Colorado!
I love the handling with the sport pack, the overall body style, power of the 4.3L. I just really like this truck!
