The Canyon SL Z85 is the base model with the base suspension (retailing at $16,025 MSRP for Regular Cab 2WD Z85). It comes standard with air conditioning, AM/FM radio, and 15-inch aluminum wheels. The front seats are a split-folding cloth bench, the floor covering is vinyl, and rear jump seats for extended cabs cost extra ($45). The SLE ($17,140) adds or substitutes front bucket seats, a floor console and armrest, color-keyed carpeting, CD player with MP3 capability, a standard rear seat on extended cabs ($20,260), and a leather-wrapped tilt wheel and cruise control on extended cab and crew cab ($21,290) models.

The Z71 High Stance off-road package increases the ground clearance by more than three inches. Z71 also adds larger color-keyed fender flares, P265/75R15 on/off-road tires, a locking rear differential, and, on 2WD models, traction control. Z71s with 4WD get skid plates and tow hooks. Ordering Z71 boosts the price of an SL Canyon $1,700-$1,800, but the package includes SLE goodies such as the bucket seats and CD player. Adding Z71 to an SLE ups the price anywhere from $2,000-$4,100, depending on cab style and how many wheels are driven. A 4WD SLE Crew Cab with Z71 retails for $28,020.

Side-curtain air bags are optional ($195-$235, depending on the cab style). A power convenience group (windows, locks and mirrors) is standard on Crew Cabs and optional ($500) on other SLEs. New Gen 6 OnStar ($695), with improved hands-free operation, is offered on SLE only. Leather-upholstered, heated, and power adjustable driver and front passenger seats ($1,495) are available as a package on crew cab and extended cab models during the 2005 model year, and a sunroof will be available.

Commercial fleet models are also available with steel wheels and skinny tires (starting at $15,045).
