Renting the 2021 GMC Sierra AT4

Courtesy car: the 2021 GMC Sierra AT4. Here is the car in plain words, and how renting one from CarmaCars works. After a collision, your insurer may pay for the rental once your adjuster approves it. When your adjuster approves a rental, we can bill your insurance company directly.

The Sierra and Knobs

Around Knobs you will also find Johnson Crossroads, Elmhurst and Union.

What the figures tell you

The powertrain to know here 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.

Its combined rating is 9.9 L/100 km, which means roughly 30 litres for 300 km. Per 100 km, plan on roughly $15.35.

Space and size

It is built for loads that would never fit in a trunk.

Who the Sierra suits

It suits a stretch between cars, by the week or the month. It suits moving day, renovation runs and anything that needs an open bed.

Rent it from us

Your request can name this exact car; the offer confirms what we can give you. None in our fleet right now; ask and we look for one for your dates. Similar cars are listed below if you need one now. Delivery and pickup are both options across the Toronto area.

What to have ready

We rent to drivers aged 18 and up who hold an Ontario G2 or G licence. Drivers under 26 can rent with a young driver fee each day. A credit card in your name is needed, except on cars marked "no credit card needed", which take debit.

Third-party liability is in the rate; for the car, bring OPCF 27, use your card's benefit, or add the CarmaCars Protection Plan. Expect a deposit before every rental; its amount is set by the car. Each extra driver is checked the same way and signs the rental agreement.

What to expect when you book

It begins with your request, sent online in a few minutes, with no payment. A person checks the request and sends you an offer with the full price. An offer is valid for 24 hours, and you pay only when you approve it.

You can see every car's calendar and rates before you send anything. A single booking can run up to 365 days. For longer, it renews month after month. Allow 2 hours or more between your request and the pickup time.

Questions first?
