    The 2021 Honda Civic Si for buyers

    We are a rental company, not a dealer, so there is no 2021 Honda Civic Si for sale by us right now. Here is the 2021 Honda Civic Si for buyers: fuel use, size, recalls and a test drive that lasts a week.

    Before you sign for the Civic

    Ask the seller for the service records of this exact car. There are 4 NHTSA recall campaigns on file; a dealer can check by the VIN whether each was done. Owners filed 161 complaints with NHTSA, most often about steering, forward collision avoidance and electrical system; have those parts checked. Check whether every recall was done, by the VIN, before you pay.

    Engine and fuel

    The powertrain to know here is the 1.5L 4-cylinder turbo, with front-wheel drive. It runs on regular gas. With front-wheel drive, the weight of the engine sits over the driven wheels, which helps in winter.

    At 6.9 L/100 km combined, a 300 km drive takes roughly 21 litres of fuel. Per 100 km, plan on roughly $10.70. EPA puts its fuel cost at US$1,950 a year for 15,000 miles at US prices.

    How big it is

    It is a straightforward car to drive, park and live with. Luggage space is 736 litres, enough for bulky luggage, a stroller or sports gear.

    Who rents the Civic

    It suits anyone who needs a car for a few days, a week or a month without buying one. It suits a family trip where everyone and everything fits in one car.

    Try before you buy

    A test week in the Civic tells you more than any review. Rent the Civic for a week, or up to 365 days, before you commit to buying one. Renting first costs a fraction of the price of buying the wrong car.

    Money matters

    At our price setting, 100 km costs about $10.70 in fuel. Ask what a set of tires costs for this trim; sizes and prices vary. A 1,000 km month costs roughly $107 at our price setting.

    Which one to look for

    Ask the seller which trim it is; badges can be swapped and options vary. Set a budget that includes tax, licensing, insurance and the first set of tires. Write down the VIN of any car you consider; it unlocks the recall and service history.

    A note on Knobs

    Knobs is about 692 km from Toronto, outside our delivery area. If you are starting from Toronto, rent the car here and drive it to Knobs.
