Had a great experience with the texting of a salesman and then the test drive!
Optima is a great car for the money!
Just traded in my 2013 for a 2018 with less than 18,000 miles on it. I loved my Optima and wanted another. This one is nice, but missing the heated steering wheel my other EX had. I like the looks of the cabin on my 2013 better than this one, but it’s not bad. It’s a smooth comfortable ride, good on gas and has some nice safety features. Definitely not disappointed.

Jon A was a gem to work with.
Jon A was a gem to work with. He bent over backwards to find deal/price that suited me. He drove my car home that evening, so I didn’t have to find someone who could meet me at the lot later in the week. He researched and finally bought a charging cord for my new, leased EV (didn’t COME with a cord!! What’s up with that, Kia??). Couldn’t have been nicer and more helpful.
I love my 2018 Kia optima
I just purchased a 2018 Kia optima from a used dealership at first I was concerned. But it only has 48,000 miles on it. Now 51,000 I always thought Kia was a girl car. But as a man. I love it. It has plenty room in the back. The car runs smoothly and I like the safety alert it gives when another vehicle is to close on you. I didn't want to drive it to work but the gas mileage is much better than my 2004 Ford escape . I've had my Kia almost a month now and I'm still trying to figure out how to work the features. Yes I recommend this car. Even if you get one with 100,000 miles on it. It would still run great

2018 Kia Optima Is One Sweet Ride
As a former GM owners we went into buying our next used car with an open mind. I knew Kias were known for their reliability and overall value, but until we took this car for a test drive, we weren't really aware of how good theses cars got. It's quiet rides real well gets great mileage...around 38-40 on the highway, upper 20's around town, it's the FE edition or Fleet Edition, it has a ton of features including, keyless entry, pwr windows, locks and mirrors, carplay, heated mirrors, I could go on and on but this car is great and looks great too. We bought it used a year ago with just under 46000 miles. the bottom line is when looking at used cars check out the Optima. You won't be disappointed.

In October 2020 I purchased my 2020 Ford Explorer ST at
In October 2020 I purchased my 2020 Ford Explorer ST at Koons Sterling Ford and have loved every minute of driving it. I've had it in for regular maintenance and recalls at the dealership but just recently on September 26, 2025, I had my best experience when I brought my Explorer in for a new battery. I had the pleasure of having Bradley Cadenas as my service rep and was very impressed with his professionalism and his outstanding product knowledge regarding my Ford Explorer. I wasn't aware of the FordPass reward points I had accumulated, and Bradley was very helpful in helping me manage these and applying them towards the cost of the new battery and related service work. I felt like I got the "red carpet" treatment and look forward to working with Bradley in the future--he is a credit to the dealership and particularly to the service department. Keep up the good work!
More than meets my expectations for safety
I like it. It has a number of safety features as well a great radio with car play, panoramic glass roof, heated and cooled seats and good gas mileage

First time at Cochran Monroeville GMC a very pleasant
First time at Cochran Monroeville GMC a very pleasant experience from beginning to the final deal. Salesman Darius was very easy to deal with making sure my buying experience was stress free. During the final numbers of the deal he explained everything and made sure I was pleased. Lucas Anderson in Finance was very proffessional and efficient. Near the end of my experience Sales Manager Dale Taylor checked with me making sure I was totally satisfied with my deal.

Brent Robken offered a great buying experience. I have purchased many cars but this had to be the best purchase ever. Brent made everything easy to understand and I'm sure that I wouldn't have purchased this car if not for him. I would highly recommend Brent Robken to anyone looking for a car.
