Executive car service and the 2021 GMC Sierra AT4

Executive car service and the 2021 GMC Sierra AT4: the figures first, then how to rent it from CarmaCars. Chauffeur bookings are by the hour, two hours minimum; send a request and we reply with the vehicle we can offer and the price.

Knobs and the Sierra

The pages for Johnson Crossroads, Elmhurst and Union cover the areas next door.

Engine and fuel

The engine is the 3.0L 6-cylinder turbo, with four-wheel drive and a 10-speed automatic. 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.

A combined rating of 9.9 L/100 km works out to about 30 litres per 300 km. In energy, every 100 km costs about $15.35 at our price setting.

Living with the Sierra

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

A good match for

It suits anyone who needs a car for a few days, a week or a month without buying one. It suits a stretch of weeks between selling one car and buying the next.

Rent it from us

Ask for this exact car in your request, and we tell you what we can offer. Meanwhile, 6 similar cars are listed below. This exact car is not in our fleet at the moment; a request asks us to look for one. Pick it up from us for free, or have it brought to you.

The booking steps

Requests come first at CarmaCars. You name the car and the dates, and we take it from there. A person replies with an offer priced for your dates, not an estimate. The booking is confirmed when you approve the offer and pay it.

The rates you see on a car's page are the rates in your offer. Book one day, one week, or up to 365 days at once. Requests for later the same day work when there are at least 2 hours to spare.

The rules, briefly

If you are 18 or over and hold an Ontario G2 or G licence, you can rent. Under 26? You can rent, with a daily young driver fee shown on the car's page. Payment is by a card in your name, shown with your licence at pickup.

Before pickup, choose how damage to the car is handled: your auto policy (OPCF 27), your credit card's rental benefit, or the CarmaCars Protection Plan. The deposit is separate from the rental price and is returned after the rental. Extra drivers are welcome; each one is checked and signs the agreement.
