Mike Cole took is fantastic and made a stressful
Mike Cole took is fantastic and made a stressful situation easy. My mom came in and he walked her through the process and was not pushy at all. He really made things enjoyable...well as enjoyable as buying a car can be. But we will 100% come back to Dave Arbogast and work with Mike in the future.

David Scott Lee GMC is the best in the Biz.
David Scott Lee GMC is the best in the Biz. I have owned 6 GMC yukons over the past 20 years and the last 3 I have purchased from Scott Lee GMC. They have the highest level of customer service that I have ever experienced with any of the dealerships that I have worked with. They are my lifetime GMC dealership.

Honest, courteous service with no pressure from the sales
Honest, courteous service with no pressure from the sales person. The price of the GMC Canyon Denali and the value of my trade was more than fair. It was so good I drove four hours to get there and I’m glad I did. Thanks to Doug Lee and the entire staff at McGovern GMC for a great Truck buying experience.

I drove over 1,000 miles to come to this dealership and I’m glad I did. They took care of us quickly and were very communicative throughout the whole process. They sent me pictures and videos so that I could know what I was getting even with being far away. Great group of people and very friendly and hospitable. Would definitely recommend this dealership. Thanks Staton for the easy car buy.

I went in knowing exactly what car I wanted to test drive
I went in knowing exactly what car I wanted to test drive and had an appointment with Jean (John) Venant on December 27th. The car (2024 Mazda CX-5) was waiting for me when we arrived. Our salesman was a great guy & seemed knowledgeable about my particular vehicle. It didn't take me long to decide to buy the car on the spot. Baltimore in the financing department fought very hard to get me the best rate/deal available. They even gave me far more for my trade in that I was anticipating. Everyone throughout the (seemingly painless) process was great to work with. We felt very valued. My only "complaint" is the sticker shock I had when I saw all the "dealer fees" on the bill of sale. Many things (window tint, fabric protector, etc) were all things that you only typically see when buying a brand new car and not when buying a used car. And, with any used car purchase, I made sure to get the extended warranty. That's just smart no matter which dealership you buy from. However, I am concerned a bit to read very mixed reviews of the EasyCare warranty company, as it seems they only approve HALF of the claims submitted. Fingers crossed.

My experience with Kirksville Motors has been exemplary.
My experience with Kirksville Motors has been exemplary. From the initial communication regarding my interest in the vehicle I ultimately purchased to the seamless sales process, every interaction was handled with professionalism and attention to detail. The staff provided a personalized experience, ensuring that all my needs were met. They maintained consistent follow-ups and facilitated maintenance checks and repairs efficiently. The dealership's transparency in terms of cost and service, alongside their comprehensive warranty coverage, was commendable. Additionally, they accommodated me with a quality loaner vehicle during the servicing of my car. Such a high level of honesty and service is rare in the industry, and I could not have envisioned a better experience.
