    The 2021 GMC Sierra AT4 for buyers

    We rent cars and sell one only now and then. There is no 2021 GMC Sierra AT4 for sale by us right now. The 2021 GMC Sierra AT4 for buyers: what the numbers say, what to check, how to try it.

    What to check on the Sierra

    Ask the seller for the service records of this exact car. There are 10 NHTSA recall campaigns on file; a dealer can check by the VIN whether each was done. In Ontario, a used car needs a Safety Standards Certificate to be registered. Have a mechanic inspect a used one before you buy it.

    The figures, translated

    Its powertrain is the 3.0L 6-cylinder turbo with four-wheel drive. It runs on diesel, sold at most highway stations. Four-wheel drive helps on rough ground and deep snow; on dry roads it behaves like any other vehicle.

    It is rated 9.9 L/100 km combined: about 30 litres every 300 km. The fuel for 100 km comes to about $15.35 at our price setting. At US fuel prices, the EPA estimates US$4,000 a year for 15,000 miles.

    Living with the Sierra

    Being a pickup truck, it trades parking ease for a cargo bed.

    Best uses

    It suits a family trip where everyone and everything fits in one car. It suits a stretch of weeks between selling one car and buying the next.

    Try before you buy

    A test week in the Sierra tells you more than any review. Renting first costs a fraction of the price of buying the wrong car. A week with the Sierra answers more than any brochure.

    What it costs to run

    Ask what a set of tires costs for this trim; sizes and prices vary. The EPA estimates US$4,000 a year in fuel for 15,000 miles at US prices. At our price setting, 100 km costs about $15.35 in fuel.

    Year and trim

    A newer year is not always better; check what changed before paying more for it. Write down the VIN of any car you consider; it unlocks the recall and service history. Set a budget that includes tax, licensing, insurance and the first set of tires.
