My sales rep was JB he is the bomb diggity. Just moved to town they made my buying so successful. I'm very happy with the service that I received. I recommend anyone to purchase a car from Jim Butler finance operator Miss Mary she's great.
We bough this car used in August from a Nissan dealer.
We bough this car used in August from a Nissan dealer. There were some hidden problems that unfortunately the dealer did not disclose right away. Window regulator apparently are a problem with this car as well as engine burning oil prematurely. I performed a two-day cylinder soak and upgraded to a higher quality oil and the oil burning is no longer an issue. Apart from these problems, the car has been great for us. No other issues and the EX version is really loaded (it even has ventilated seats). Multimedia gets slow after being updated, be aware. But updates adds some features like, for example, lowering the fan speed when you get a call or ask to read a message. It is compatible with android auto and apple car play, not wireless but you can get one of those adapters.

Gus and his crew were amazing.
Gus and his crew were amazing. I bought this pickup off the internet, and they picked me up at the airport and 1 hour and 20 minutes I was headed home.
One fine company
This car now has almost 170k miles.other than normal wear and tear and some recalls the car has been excellent. The real subject here is KIA . They have been a real stand up company. In my opinion KIA has had my back. KIA will be my next purchase

Awesome!
Awesome!!!! These guys are the best!!!! Friendly, caring, attentive. Attention to detail when it comes to explaining your situation to you. Just a great atmosphere!
Not too bad!
There's pro and cons with this car. I love the fact that this car is very good of mileages save so much fuel , I lived in San Antonio and we drove this car with full tank to Corpus Christi its about 2 hours and half, almost 145 miles away, then we came back still have half full of a tank. My deslike about the car is the front passenger set, its kinda very low and there's no other way of adjusting it. ( Blind spot)When changing lane specially to your rare left side ,you literally turning your head making sure there's no other vehicle. Other than that??The car is good to drive.

Great atmosphere and Mike did an awesome job helping with the purchase of my vehicle, I would recommend Jim Butler of Fenton ,MO to anyone looking to purchase a vehicle, thanks Mike
I bought this car used from friend they did have motor
I bought this car used from friend they did have motor problem but they bought it new so kia replaced motor and my daughter drove it couple years then when she graduated I took Kia and bought her new car for her and grandkids and I have been happy with it. It's my everyday car because it gets great MPG. It's got 160k miles about 50K on new motor. So far no issues just keep her up to date on oil changes and stuff. It's 1st Kia I ever owned and I would definitely give them another go if time to buy another vehicle.

Amazing Team
I broke down in town and Hannah from the parts department spoke to me so clearly and kindly when I was looking for a part. Hannah answered every one of my questions and even sent me pictures of the parts so I could verify it was the right one. Hannah went above and beyond for me and I cannot thank her enough. I came to the dealership and met Lakelynn who graciously assisted me in getting my car serviced. It is not always easy to get same day service but Lakelynn found a tech who had time for my small repair. I am forever grateful to her for going out of her way to ask, even after another staff had concerns about same day availability (at 4pm, which is a miracle in itself)! Finally, me and my friends waited in the lovely waiting area that was clean and comfortable. After being serviced, Lakelynn came over to tell me my car was taken care of and was ready to drive off. Linda at reception checked us out and delivered a friendly smile as we paid for the services. Thank you team! Thank you so much. And a big shout out to these three women who really went above and beyond!

Everyone needs to buy their cars from Scott Brenner.
Everyone needs to buy their cars from Scott Brenner. He is helpful in everyway he finds possible and is creative in doing that. He frequently goes beyond the call of duty.
Would recommend for a cheap and reliable commuter
I've had my Optima for nearly a year now and nothing bad has happened so far, in 10 months I've put on 13,000 miles; from 74,000-87,000 miles and I haven't experienced a single issue. It looks good, runs reliably, and is comfortable on long drives. However, I feel that the acceleration is a little slow but hey, I'm 19, every teenager wants fast, but I'm really happy with my Optima and I definitely recommend it!

Highly recommend BBC to anyone looking for a reliable car at a great price! Tyler was very helpful along the way. Our Nissan Altima has been a great vehicle. Will definitely be back for future purchases!
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.

I don't ever write reviews, but will now. I've had this 2015 optima ex turbo 1.4 yrs and really performs well! Smooth ride and not bad on gas. Have had no engine problems. No issues but little head space in cabin . Anyone over 5 10 is in trouble. It feels solid/safe driving. The turbo really moves when power is needed.

Best car buying experience ever!!
Ryan helped my daughter make her first adult car purchase. He went above and beyond to make the car buying experience a fantastic experience for her. Everyone there were so friendly and down to earth with easy going demeanors. I would recommend them to anyone purchasing a car!!
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

Best salesman EVER
Thomas Grice was a great salesman. He explained the car details so well that I feel VERY comfortable taking the car home (190 miles away)!! I would suggest he is the best car salesman I’ve experienced in the 7 new cars I’ve purchased and too many to count used cars my late husband and I bought. Very professional!
Good but not great?
So my car is a 2016 Kia Optima SX 2.0 Turbo GDI. I bought it with just under 60K miles and am just below 85K now. It was burning oil, but once I replaced my pvc or pcv valve ($30 at O'Reilly's), runs like a peach. So uniquely updated and ahead of the game for a 2016. Tough saying if I would recommend it because a quick google search will tell you that the car will probably give out at 150K miles. Transmission is probably the worst I've ever felt but it hasn't given out yet. OEM blow off valve thing is sick.

Loyal customers
We recently purchased a certified pre-owned vehicle at Frank Leta Acura and this is our second purchase with the dealership. Each time we’ve received excellent customer service. Kevin Baker was our Product Specialist that helped us with our second purchase and was very instrumental in finding us the right vehicle with the options we were looking for. He was very good with follow up and keeping us updated on our vehicle. We’re really happy with our purchase and the services that we received at Frank Leta Acura!
Love this car!
Love this car! Have 45,000 miles on vehicle and have only done brakes and tires… Super happy with the way it looks and responds. Most reliable car I have owned. Would happily go to another Kia after this one!

Awesome experience.
Awesome experience. Cody was professional and easy to deal with. I came from about 45 miles away and he knew what time I would arrive to look at it and take it for a test drive. Cody was honest and very straightforward with me.

I bought this car new, and it has, and still is a great car. The fuel economy is awesome, getting 35 to 37 MPG on the highway, and the only costs have been normal costs, which include general maintenance items such as oil changes, freon, tires, and batteries. The only minor issue is that the passenger seat sets low, and the height is not adjustable.

Great Service
I bought a 22 Ford Bronco from Clement Ford in December 22 and have had on scheduled service which went great using the valet service they provide. However, what really impressed me was this week I had an issue with the bead locks on my wheels. I spoke to Jerry and Alex in their service department and they were able remove the bolts I was having issues with, allowed me to use the valet service once again, and didn't even charge me for the time. I'm very happy with my experience with them so far!
Great car for the money.
164,000 miles no issues. Car services me well. The oil usage is slight. I would get another, but KIA doesn't make them anymore. My commute is about 1 hr one way.

Good job Tom
I came in looking for a new Honda and Thomas helped me locate the exact car for my needs. Love the car and I’m glad to add it to my family ! Thanks Tom
We love the car but one major flaw.
We love our 2020 Optima. So much for the $$. Good size, ride, and ample features including safety for the money. 2nd owner and my daughters commute to college at 34-35 mpg which is good for this size car. Unfortunately too many have engine failure with 2.4L (8-10k replacement) and nearing 60k warranty end I'm going to trade for a Honda or Toyota rather than roll the dice. A shame they can't provide a bulletproof engine with an otherwise awesome car!!

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.

Beautiful Car!
I got the 2020 KIA Optima S trim. The car is great! This is my first car and the safety features helps me out a lot. The backup camera works really well thankfully because I can’t see see anything out the back window lol. I’m in the military so I drive her around a little more often than usual. The car holds up well. The car is very comfortable as well I drive her back home (15hrs) and have no issues at all. The fuel economy is great as well get around 530 miles on a full tank. The car is not a race car so I wouldn’t expect that kind of performance. That being said she is pretty fast and handles great! I got mine in 2021 for about $24k with around 23k miles on it. For the money I’d definitely say it’s worth it.
