Each model comes in a variety of configurations, from basic rear-wheel-drive regular cabs to extended cabs and well-equipped four-wheel-drive crew cab models. In bare-bones guise, the Colorado/Canyon provides buyers with the utility of a truck and little else, though antilock brakes, a radio, a tilt steering wheel with cruise control, and air conditioning are standard. Options include upgraded sound systems, side curtain airbags, and extravagancies like rubber floor mats.
