The interior for all Colorados is nowhere close to impressive, with cheap, hard plastic as the theme. It must be noted, however, that inside the ZQ8-equipped models, unique seats unavailable in other Colorado models are rather nice.
Body styles of the 2010 Colorado include a regular Cab, Extended Cab (with short reverse-opening doors), and Crew Cab (with four regular forward-swinging doors). Crew cabs come with a five-foot cargo box, while other Colorados feature a six-foot bed. For those who need rear space, the six-foot "long" bed won't carry a 4x8 sheet of plywood, and four-door Colorados have only a five-foot, one-inch bed anyway.
Car and Driver says, “In its latest comparison test appearance, the Colorado finished last out of five trucks and was flayed for its rental-car interior, unrefined engine, and upright rear backrest.” Edmunds isn’t a fan of the Colorado’s interior either, explaining that "seating comfort and cabin materials still leave much to be desired." Chevrolet loses marks for giving "the impression of being cheap," with Edmunds also noting "sub par materials, an abundance of hard plastic and mediocre seat comfort."
Automobile Magazine finds that “the front bucket upgrade (a 60/40 split bench is standard) brings seats that feel convex instead of concave,” explaining that “driving stints longer than two hours will have you speed-dialing your chiropractor for relief.” ConsumerGuide is pleased with the front part of the 2010 Chevrolet Colorado cab's interior, pointing the "lots of legroom and headroom" and seats that are "adequately comfortable for long drives." Kelley Blue Book agrees, claiming the "seats offer firm bottoms and good lumbar support" and that "the cloth fabric is both durable and comfortable."
ConsumerGuide faults the Colorado’s rear seats for being hard, undersized, and uncomfortably upright. Getting to them is also a challenge, as "entry and exit is difficult through small door openings." As with legroom, storage is limited, although this is less of a problem on the Extended and Crew Cab models. TheCarConnection.com also finds adequate space in the Crew Cab’s backseats for two adults, although the cushions are a bit flat.
It can be said that build quality is commendable despite the use of cheap materials, with Kelley Blue Book reporting that "even over washboard roads, the Colorado exhibited no sign of dash-rattling or squeaks." Edmunds finds that the Colorado remains "relatively quiet around town," with "wind noise around the doors picking up at highway speeds."
