For the third time in the row, I have received an
For the third time in the row, I have received an excellent sales experience from Union County Kia. And don't forget Everett and Eddie, as well as Noah. They are all fantastic salespeople. And in case anyone was wondering, Brandon is still the MAN in financing! He got my paperwork done with an even lower price than the one I was quoted! Salena is the best in the service department. She's taken great care of the new vehicles that I have purchased over the years. They all get the job done with as little hassle as possible. I thank God for everyone I've mentioned. People come from miles around because their service is legendary! I can witness to that as a fact! UCK IS THE BEST! If you're in the market for a new vehicle, don't pass Union County Kia by!
This truck has a jerk when changing gears sometimes.

I highly recommend this dealership to anyone considering
I highly recommend this dealership to anyone considering buying a vehicle. I live in Colorado and found one of their vehicles online. When I called, William picked up the phone and gave me honest answers to every concern I had. Soon after, I was contacted by the Sales Manager, Jason, who made me feel even more confident about the process. They picked me up from the airport, and everything — absolutely everything — was exactly as promised. From start to finish, this was hands down the best car-buying experience I’ve ever had. These guys are true professionals. If they give you their word, you can trust they’ll stand by it. Going forward, this will be the first dealership I check when shopping for any future vehicles — especially high-end ones — because I know I’m dealing with a team that values honesty and integrity above all. Thank you again for an outstanding experience!

Contacted Larry Goode to purchase a new Kia Sorento for our school system. First class from start to finish. He stayed in contract with me for several days as we worked through the process. Vehicle was ready to go for pick up on November 28, 2025. Asked him to have all paperwork ready for me and he delivered as promised. I was in and out in less than an hour.
