Amazing service!
I had amazing customer service and financial advice. I felt so great about my decision and confident that I was getting the best deal I could. As a first time buyer, I was nervous, but felt very reassured by the staff! Highly recommend!

I purchased the new 2025 Kia K4 EX during late August for my wife to help celebrate our 55th wedding anniversary, and she simply just loves driving the car with all of its modern safety high-tech features, its comfort, and impressive driving performance. I've nicknamed the car "The Batmobile" with its Aurora Black Pearl exterior paint and stylish features that make this car stand out from other sedans that are in the cost-effective $20,000 - $30,000 price range. Plenty of room inside the car, a quiet smooth ride, and adequate acceleration whenever may be needed (e.g., entering onto a highway). The car comes with Kia's standard 5 year, 60,000 mile full warrantee, and 10 year, 100,000 mile powertrain warrantee which is still very generous of KIa.

Amazing Service Department
Chris Johnson in the service dept. was awesome! I had a major engine problem and talked to Chris who instructed me to bring my car in so he could look at it. To make a long story short, Chris and Hyundai stood behind their product and completely took care of my problem! Can’t say enough good things about Chris and Hyundai! Thank you!

Great Service!!
I was looking at buying a 2014 Toyota Corolla and Willie was the 1st person I talked to at the dealership. There was absolutely no pressure from the start of the conversation to even buy the vehicle. Before we even talked about anything sales wise he recommended that I take a look at the car and test drive it before anything to make sure it was everything I wanted. Even during the test drive, we didn't talk about buying the car, it was just a normal conversion. After test driving the vehicle I needed to think about it and even then Willie never tried to keep me at the dealership to try and buy the car. He followed up with me a few days later to see how everything was going and even put the car on hold for me so no one else would take it/buy it. I ended up not buying the vehicle this time, after thinking about it for a few days. The customer service I received and the atmosphere that, i'd have to say Willie created, was Fantastic and would highly recommend asking for him if you are looking for a car. I couldn't be more satisfied with the service I received, and will be going back to him towards the end of the year to then purchase a vehicle.
