Jim Butler Kia review

Our sales consultant, Ben Gordon, was great!

Our sales consultant, Ben Gordon, was great! He took the time to understand what features we were looking for and showed us cars in a variety of price ranges. We felt no pressure to buy. Ben was able to get us the maximum value for our trade-in and we left with a car. They processed the sale quickly. I would recommend the dealer and working with Ben.

2025 Kia K4 LXS review

Great car at its entry price.

Great car at its entry price. Rented both Honda Civic, Volkswagen Jetta and Kia K4. Drove all for week (7 days). The Kia won hands down. Bought Kia K4 for $23,400 over 3 months and it has better warranty than its competitors. Safety and accessories are part of Kia’s factory standard install compared to up charges from Honda and Volkswagen. Love interactive cruise control and its Saftey features.

Moe is Exceptional

Moe was an exceptional salesman. Although we decided to purchase elsewhere we highly recommend him. He was kind, straightforward and goof natured. He did not pressure us and was a great understanding listener.

2025 Kia K4 EX review

I have owned my K4 EX for about a month now.

I have owned my K4 EX for about a month now. It has been a great car! I think that the most fitting word for this car is value. You get A LOT for the money. I got my EX for under $25k out the door and for that I got a car that has a great design, awesome technology (wireless car play, huge touchscreen, updated safety features etc), fantastic fuel economy (40+ on the highway) and a very comfortable ride. This feels like a car that should cost at least $10k more than it does. I highly recommend this car.

Suntrup Kia South review

Bought the car I had researched from Suntrup KIA.

Bought the car I had researched from Suntrup KIA. The salesman Moe was way more than helpful.every one I dealt with was super helpful friendly and seemed very genuine. Moe spent as much time as I wanted showing me features. And even would explain more about her telluride that she bought somewhere else. I have bought many cars in my life. But I can honestly this was my best car buying experience. They all did try to meet my terms and I left feeling I got a great deal. And I did.

Suntrup Kia South review

I recently had the pleasure of purchasing a car from

I recently had the pleasure of purchasing a car from Suntrup Kia South, and I can’t express how satisfied I am with the experience. Despite being a thousand miles away, their professionalism, transparency, and warmth made me feel right at home. From the moment I connected with Moe Saad, I knew I was in good hands. Moe exemplified the epitome of a top-notch car salesman, providing me with reassurance and guidance every step of the way. My search for the perfect EV9 led me to many dealerships, but none matched the integrity and authenticity of Suntrup Kia South. Moe and his team went above and beyond, offering red carpet treatment without the need for an actual red carpet. Even while under the weather, Moe ensured a seamless transaction, passing the baton to Dzenis, who continued the stellar customer service. From start to finish, every detail was meticulously handled, including a thoughtful conversation with sales manager Dave, who ensured my satisfaction was met at every turn. In an industry often plagued by deceit and gimmicks, Suntrup Kia South stands out as a beacon of honesty and excellence. It’s rare to find such a level of service and transparency, and I can confidently say this was the best car-buying experience I’ve ever had. Despite the distance, I’d make the journey again without hesitation. If you’re in the market for an EV9 or any vehicle, do yourself a favor and visit Suntrup Kia South. You won’t be disappointed. Hats off to Moe, Dzenis, Dave, and the entire team for exceeding expectations and setting the bar high for customer satisfaction.

I purchased a Kia Telluride from them. They were excellent to work with. No nonsense, knowledgeable, respectful of my time, have competitive pricing, smooth, buying process, and great product selection. I highly recommend them. Ask for Doug Willis, he’s great to work with.
