Thinking of buying the 2018 Kia Optima?
CarmaCars is a rental company and does not have the 2018 Kia Optima for sale right now. Rent one for a week first, or ask us to look for one. This page helps you judge the 2018 Kia Optima before you buy one anywhere.
What to check on the Optima
A private seller in Ontario must give you a Used Vehicle Information Package. Have a mechanic inspect a used one before you buy it. NHTSA has 243 owner complaints on file, mostly about engine, unknown or other and electrical system. In Ontario, a used car needs a Safety Standards Certificate to be registered.
The figures, translated
The engine is the 2.0L 4-cylinder hybrid, with front-wheel drive and a 6-speed automatic. As a hybrid, it does best in stop-and-go traffic, where the electric motor does more of the work. 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 5.6 L/100 km, 300 km takes about 17 litres. A 300 km weekend costs about $26.04 in energy at our price setting. At US fuel prices, the EPA estimates US$1,600 a year for 15,000 miles.
How big it is
As a large sedan, it has a closed trunk that keeps luggage out of sight. EPA lists 368 litres of luggage space, enough for about two large suitcases and a few soft bags.
Is it right for your trip?
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.
A longer test drive
A week of your own driving tells you more than a test drive: the commute, the parking, the fuel. Rent it, live with it for a week, and decide with real experience. Rent the Optima for a week and see how it fits your life.
Money matters
Tires, brakes and batteries are the regular costs to budget for beyond fuel. At our price setting, 100 km costs about $8.68 in fuel. Ask what a set of tires costs for this trim; sizes and prices vary.
Which one to look for
Ask the seller which trim it is; badges can be swapped and options vary. If you are unsure between two options, rent one of them for a week first. Decide what matters most first: fuel use, space, or the price you can pay.
