I've had this truck for only 5 months but it has been great so far. It gets great gas mileage (22highway) for a 4x4 truck and 5 cylinder engine (also comes in 2x4, and 4 cylinder engine). This truck is small, drives more like a car than any other truck I have driven, very manuverable and convenient. Compared to any other trucks on the market I think that the Colorados and Canyons (GMC same thing, different label) are the best deal.
4x4 is button on dashboard, very easy compared to older trucks (2x4 models have traction control button). Automatic lights, when it's dark the lights turn on, etc. Lots of options, I got lockable tanneau cover, great for everything. Once again, gas mileage. Really good looking.
I like bench seats better, I dont think they offer these. The locking cover gets stuck when its below freezing, annoying. The mud flaps should be included. More spatious cab would be nice. CD player and speakers are pretty much bad quality.
