Stress free, best dealership we have bought from.
We have FINALLY found OUR dealership! The entire process was a welcomed change, Thank You! We never felt pressured, stressed or had others expectations weighing in on our decision. Chevis was our salesman, he worked for us to get what we wanted at the price we needed, without his effort our new AT4 wouldn't have been a reality. Alicia in the business office was as down to earth and chill as you could ask for. She didn't pressure us at all, let alone hound and demand like my other experiences with final documentation process of vehicle buying. The GM, made time to get to know us and made sure our deal was enjoyable. All in all, in the future, we will drive hours to this dealership for the service, product knowledge, and professionalism.
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

747 miles for 21 year old truck
Jim Luttrell called me on a truck I was interested in when the sell fell through for previous buyers. Was already in Louisville looking at another. Took the chance to go look at it. Total 747 miles one way from my house. Easy process, glad he wore his mask. Bad thing....COLD weather!

YOU GUYS ROCK!!
I walked in and was immediately greeted. The guy that helped me had very great customer service skills and was very friendly. I have a crystler 300 and the oil needed changed and transmission fluid checked. I was expecting to pay around $250-300 bucks but got a discounted price and only paid $165. I definitely will be going back when service to my vehicle is needed again

Cool People, Great Service
I had to get a lot of work done on my car -a Fiat 500 L- New headlight, oil change, back brakes, new tires… Scott was very friendly, super helpful, and respectful. He explained in simple terms what I needed and when The repairs were complete, Rolando washed my vehicle and scraped the shoe polish message from my back window. Larry was super cool when he brought my vehicle out. I really enjoyed the waiting room because they had on some old cowboy show and had a library full of books we customers could read. Cookies and coffee made the wait great. When my car had to be in for much longer to get the brakes fixed, I got a great loaner car, a Fiat Abarth Turbo. Overall, highly recommended. Fiats always come with a little sticker shock so that was to be expected.
