    The 2021 Honda Civic Si for buyers

    CarmaCars is a rental company and does not have the 2021 Honda Civic Si for sale right now. Rent one for a week first, or ask us to look for one. We are not a lender and do not arrange loans. A monthly rental can cover the time while you arrange financing with your bank. This page sets out the 2021 Honda Civic Si for buyers, in plain words.

    A buyer's checks

    A pre-purchase inspection at a shop you choose is money well spent. In Ontario, a used car needs a Safety Standards Certificate to be registered. Check whether every recall was done, by the VIN, before you pay. Look at the tires, brakes and battery; they are costly to replace.

    Engine and fuel

    It is powered by the 1.5L 4-cylinder turbo, with front-wheel drive. The turbo gives a small engine the pull of a bigger one when you need it. 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. At our price setting, driving 100 km costs about $10.70, and a 300 km weekend about $32.10. EPA puts its fuel cost at US$1,950 a year for 15,000 miles at US prices.

    Who the Civic suits

    It suits a family trip where everyone and everything fits in one car. It suits a work trip where a reliable car matters more than anything else.

    What to expect from the Civic

    It is a straightforward car to drive, park and live with. The trunk holds 736 litres by the EPA's count: bulky luggage, a stroller or sports gear.

    Try before you buy

    If the Civic is in our fleet, its page shows the rates; if not, a similar car helps you judge. Renting first costs a fraction of the price of buying the wrong car. If it is in our fleet, rent it; if not, a similar car gives you a feel for the class.

    Year and trim

    If two trims share a powertrain, the difference is equipment, which you can check in person. Ask the seller which trim it is; badges can be swapped and options vary. Decide what matters most first: fuel use, space, or the price you can pay.

    The cost of driving it

    Get an insurance quote for this exact model before you buy; rates differ a lot between models. 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.

    Renting for Knobs

    If you need it in Knobs itself, send a request and we will tell you honestly whether we can help. Knobs is about 692 km from Toronto, outside our delivery area.
