    Thinking of buying the 2021 Honda Civic Si?

    We rent cars and sell one only now and then. There is no 2021 Honda Civic Si for sale by us right now. This page sets out the 2021 Honda Civic Si for buyers, in plain words.

    A buyer's checks

    Owners filed 161 complaints with NHTSA, most often about steering, forward collision avoidance and electrical system; have those parts checked. Ask the seller for the service records of this exact car. Look at the tires, brakes and battery; they are costly to replace. A pre-purchase inspection at a shop you choose is money well spent.

    What the figures tell you

    Power comes from the 1.5L 4-cylinder turbo, driving through an automatic (CVT). It runs on regular gas. With front-wheel drive, the weight of the engine sits over the driven wheels, which helps in winter.

    By the EPA's combined rating of 6.9 L/100 km, 300 km takes about 21 litres. Driving 300 km costs roughly $32.10 at our price setting. The EPA estimates US$1,950 a year in fuel for 15,000 miles.

    Who rents the Civic

    It suits a work trip where a reliable car matters more than anything else. It suits a stretch between cars, by the week or the month.

    What to expect from the Civic

    As a large sedan, it is easy to drive and park in the city. Its 736 litre trunk is enough for bulky luggage, a stroller or sports gear.

    Rent it for a week first

    Rent the Civic for a week, or up to 365 days, before you commit to buying one. If it is in our fleet, rent it; if not, a similar car gives you a feel for the class. Rent the Civic for a week and see how it fits your life.

    Narrowing it down

    Look at a few listings of the same year and trim to get a feel for fair prices. Compare the Si with the other trims of the same year before you decide. If you are unsure between two options, rent one of them for a week first.

    What it costs to run

    Ask what a set of tires costs for this trim; sizes and prices vary. At our price setting, 100 km costs about $10.70 in fuel. The EPA estimates US$1,950 a year in fuel for 15,000 miles at US prices.

    Renting for 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.
