The 2018 Kia Optima for buyers
No 2018 Kia Optima is for sale by CarmaCars at the moment; this page helps you judge the car before you buy one elsewhere. We are not a lender and do not arrange loans. A monthly rental can cover the time while you arrange financing with your bank. Before you buy the 2018 Kia Optima, see the figures and the checks worth doing.
What to check on the Optima
Ask the seller for the service records of this exact car. Owners filed 243 complaints with NHTSA, most often about engine, unknown or other and electrical system; have those parts checked. In Ontario, a used car needs a Safety Standards Certificate to be registered. A pre-purchase inspection at a shop you choose is money well spent.
Reading the spec sheet
Power comes from the 2.0L 4-cylinder hybrid, driving through a 6-speed automatic. As a hybrid, it does best in stop-and-go traffic, where the electric motor does more of the work. Front-wheel drive is the usual layout for cars this size, predictable in the rain and the snow.
Its combined rating is 5.6 L/100 km, which means roughly 17 litres for 300 km. At our price setting, driving 100 km costs about $8.68, and a 300 km weekend about $26.04. EPA puts its fuel cost at US$1,600 a year for 15,000 miles at US prices.
Best uses
It suits stop-and-go driving and rideshare or delivery work. It suits a stretch of weeks between selling one car and buying the next.
Practical details
Being a large sedan, it is easy to park and comfortable on longer drives. Luggage space is rated at 368 litres: about two large suitcases and a few soft bags.
Rent it for a week first
Renting first costs a fraction of the price of buying the wrong car. Rent the Optima for a week and see how it fits your life. Nothing is charged until we confirm the rental and you approve the offer.
Choosing the right one
Set a budget that includes tax, licensing, insurance and the first set of tires. Ask the seller which trim it is; badges can be swapped and options vary. If two trims share a powertrain, the difference is equipment, which you can check in person.
The cost of driving it
Tires, brakes and batteries are the regular costs to budget for beyond fuel. The EPA estimates US$1,600 a year in fuel for 15,000 miles at US prices. Ask what a set of tires costs for this trim; sizes and prices vary.
