    No 2023 GMC Sierra SLT is for sale by CarmaCars at the moment; this page helps you judge the car before you buy one elsewhere. Buying the 2023 GMC Sierra SLT is a big decision; here is the information we have.

    A buyer's checks

    NHTSA lists 4 recall campaigns for this model; ask the seller for proof each one was fixed. Ask the seller for the service records of this exact car. Owners filed 553 complaints with NHTSA, most often about engine, power train and structure; have those parts checked. In Ontario, a used car needs a Safety Standards Certificate to be registered.

    What the figures tell you

    The powertrain here is the 3.0L 6-cylinder turbo with rear-wheel drive and a 10-speed automatic. It runs on diesel, sold at most highway stations. Rear-wheel drive gives balanced handling; in winter, the tires make the biggest difference.

    Expect about 27 litres for every 300 km, going by its 9.1 L/100 km combined rating. Expect about $14.11 per 100 km at our price setting. EPA puts its fuel cost at US$3,700 a year for 15,000 miles at US prices.

    Living with the Sierra

    As a pickup truck, it has an open bed for things that would never fit in a trunk.

    Best uses

    It suits visitors who want a familiar car for a week in town. It suits a stretch between cars, by the week or the month.

    A longer test drive

    Rent the Sierra for a week and see how it fits your life. Renting first costs a fraction of the price of buying the wrong car. Rent the Sierra first, and buy only if it fits your life.

    What it costs to run

    Tires, brakes and batteries are the regular costs to budget for beyond fuel. At our price setting, 100 km costs about $14.11 in fuel. Get an insurance quote for this exact model before you buy; rates differ a lot between models.

    Year and trim

    If you are unsure between two options, rent one of them for a week first. Look at a few listings of the same year and trim to get a feel for fair prices. A newer year is not always better; check what changed before paying more for it.

    Renting for Seven Knobs

    If you are starting from Toronto, rent the car here and drive it to Seven Knobs. Seven Knobs is about 2,063 km from Toronto, outside our delivery area.
