Used 2018 Chevy Colorado Crew Cab

The entry-level model, known simply as Base, covers the truck basics without a lot of extras, but it still has a decent amount of equipment. It's offered only as an extended cab, and standard features include a 2.5-liter inline four-cylinder engine (200 horsepower and 191 pound-feet of torque), a six-speed manual transmission, 16-inch steel wheels, air-conditioning, vinyl upholstery and floor covering, a four-way power driver seat with manual recline, front bucket seats, a tilt-only adjustable steering wheel, power windows, a rearview camera, and a six-speaker sound system with Chevrolet's app-based MyLink system, Bluetooth phone and audio connectivity, voice controls, Apple CarPlay and Android Auto, and a 7-inch display.

There aren't too many changes when you step up to the Work Truck (WT) model, but it does come in both extended-cab and crew-cab body styles and adds fold-up rear jump seats (extended-cab models only), cloth upholstery, carpeting and floor mats.

The biggest difference between the Base Colorado and the Work Truck trim is the latter's list of available options. Essentially you can equip the Work Truck with a few tech items, optional engines and exterior trim that make it feel less basic. From the WT level on up, you can get a six-speed automatic transmission for the base four-cylinder or one of the Colorado's two optional engines: a 3.6-liter V6 (308 hp and 275 lb-ft) paired to an eight-speed automatic transmission or a 2.8-liter turbocharged four-cylinder diesel engine (181 hp and 369 lb-ft) paired to a six-speed automatic.

Notable options for the WT include remote keyless entry, cruise control, an EZ-Lift tailgate, and OnStar telematics (roadside assistance, turn-by-turn navigation, automatic crash response) and 4G LTE Wi-Fi hotspot connectivity.

If you don't want to sort through all the WT's options sheets, you can simply spring for the LT, which gets you most of the above items, plus 17-inch alloy wheels, a leather-wrapped tilt-and-telescoping steering wheel, an 8-inch touchscreen, satellite radio, in-car 4G LTE Wi-Fi, and two additional USB ports.

More options are available for the LT, with the most notable ones being heated front seats, automatic climate control, heated exterior mirrors, and forward collision and lane departure warning systems. For LT models and above, there's an available seven-speaker premium Bose audio system and a navigation system (an enhancement of the standard 8-inch MyLink interface).

For more luxury items and some mild off-road ability, you'll want to check out the Z71. It comes standard with most of the LT's optional equipment, plus it adds dark-tinted 17-inch alloy wheels, all-terrain tires (instead of all-season tires), an off-road-oriented suspension, a locking rear differential, hill descent control, unique cloth and simulated leather upholstery, and other model-specific trim pieces.

Even with the off-road-oriented suspension, the Z71 is still more oriented toward street use. For more ability off the beaten path, the ZR2 is your truck. The ZR2 has a raised suspension with special dampers, bigger all-terrain tires, fender flares, special bodywork for improved approach and departure angles, a spray-in bedliner (optional on other trims) and an electronically locking rear differential. Chevy offers the V6 or the diesel engine for the ZR2.
