2020 Optima, Edmunds review:
“I have had my Kia Optima FE … for 6 months now and am quite happy with it. I was driving a 2005 Highlander and was not sure if I would like a sedan, but the quieter and smoother ride won me over. Apple CarPlay is great. I like all the safety features it has. Around town I get 26-27 mpg according to the dash info and on the highway, if there are no slowdowns or stops, 40-50 mpg. Update 1/23. I am still happy with this car. No problems other than the logo on the hood has peeled.”

The 2019 Optima is another solid choice. Its more affordable than many of its rivals and is great for commutes and highway driving.
It boasts handsome styling, plenty of storage compartments, and an abundance of safety tech.

2019 Optima, Edmunds review:
“This was such a good option. The car practically drives itself on the highway. It’s modern and turns heads. The headlights could be better and I plan on replacing the bulb with LED headlight. The seats are comfy and the car has a nice acceleration. We chose this over the Camry and wouldn’t go back. This is way better and it has better reviews than even a Honda CRV!”
2018 Kia Optima
The 2018 Optima is a great midsize car that provides lots of value for its price.
It has more features than many of its rivals, a classy interior, and hybrid and plug-in hybrid models to choose from too.

2018 Optima, Edmunds review:
“This car is super spacious, great on gas, and has a great exterior look to it! I receive so many compliments on my car and I love taking it for a drive. Sometimes the USB port for ApplePlay acts a little funky but I usually unplug and plug my USB charger right back in and it works fine after that. My last car was a Kia Forte which I loved as well but the Optima was the perfect upgrade for me. Overall, Kia has treated me great”
2017 Kia Optima
The 2017 Optima is the second entry of the 4th generation introduced for 2016. It is another excellent choice when shopping for an affordable and reliable midsize car.
In comparison to older generations, the 4th generation is sleeker in design, offers slightly improved performance, and has notably more tech and safety features.
The 2017 model is largely a carryover but there are a few revisions, including upgraded headlights for certain trims (xenon to LED) and the addition of optional packages for most trim levels.
This model has received far fewer complaints than many of its direct predecessors which we cover in the worst years section.
There are 3 engine options: 1.6-liter (178 horsepower), turbocharged 2-liter (245 horsepower), and 2.4-liter (185 horsepower).

2017 Optima, Edmunds review:
“ … 8000 miles and still would buy again. Two long road trips and daily to work. This car is so comfortable and useful. It has amenities for both front and rear passengers. Drives smooth as a top and has the pick up when you need it. There is nothing we don’t like. Nothing. To date, there is nothing we would add. It has it all!! Safety features have been useful and come into play every time we drive the car…”

2010 Optima, Edmunds review:
“I purchased my 2010 KIA Optima a year ago and I couldn’t be happier. It was one of KIA’s rentals with 12,000 miles on it and in pristine condition inside and out. I’m getting about 30 mpg around town. It handles beautifully and I feel safe and secure driving it. My mechanic was very impressed with it when I took it in for an oil change. Said I made a smart purchase. I’m an old woman now, 67, and this will probably be my last car but if I ever have to buy another car I would buy this one in a heartbeat.”
2009 Kia Optima
The 2009 Optima may not have the most modern technology, but it is one of the most reliable model years to have ever been produced.
It boasts excellent crash test scores, numerous safety features, a spacious backseat, and responsive driving characteristics.

2009 Optima, Edmunds review:
“Had for 6 months and have put 4,000 miles on it. Had a 2006 sportage and saw the optima and had to have it. I am blown away at the attention it gets. People are always telling me they love its looks and the red color is sharp. I just smile when I pull up beside a accord or Camry and think to myself I saved thousands and have an equal car. The optima feels smooth and plenty of power from the I-4 it only has a few less horse power than the v-6, save a few bucks and buy the I-4. The trunk really holds a lot and the car is comfortable on long trips. The gas mileage is as advertised which many cars do not match up. So we are very pleased. We do recommend kia to everyone we know.”
2006 & 2005 Kia Optima
The 2006 and 2005 Optima’s make an excellent choice for those on a very tight budget. They are the final installments of the first generation and whilst they are a bit dated in terms of design and features they have proven to be very reliable cars.
These models have been praised for their athletic handling, spacious cabin and comfortable seats.
These models come in 2 trims, LX and EX and there are 2 engine options a 2.4-liter 4-cylinder and a 2.7-liter V6.

2006 Optima, Edmunds review:
“This car replaced a Buick Century and I must say it has many better features than my GM auto did. It is roomier, much better protection for all riders, handles like a dream, and has the very best finish I’ve every seen on a new car. I’ve owned many new cars in my lifetime (I’m 75 years old) and this KIA is the best!”
