    About the colour

    Want silver? Put it in the request. Our silver cars, when we have them, appear first in the list. A silver car can be requested, but never promised before we confirm.

    The numbers in plain words

    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. For 1,000 km, budget about $153.50 at our price setting.

    Best uses

    It suits a work trip where a reliable car matters more than anything else. It suits a weekend away when the train does not reach where you are going.

    Room inside

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

    Getting one from us

    What to bring

    You need to be 18 or older at pickup, with an Ontario G2 or G licence valid for the whole rental. Drivers below 26 pay a fee each day of the rental, and older drivers pay none. We need to see the card and the licence of the person renting.

    Choose before pickup how damage to the car is handled: your policy with OPCF 27, your card's rental benefit, or the CarmaCars Protection Plan. The deposit amount depends on the car and is shown on its page. Before confirming, we verify the licence and identity of each driver.

    How a booking comes together

    You ask for the car you want for the dates you need. The request itself is free. An offer follows, with the car we confirm and the full price for your dates. Payment happens only after you accept the offer.

    Each car has its own page with its photos, its rates and its calendar. The longer the booking, the lower the rate a day tends to be. Plan for at least 2 hours between sending the request and picking up the car.
