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.
READ PLEASE I love my Terrain.
READ PLEASE I love my Terrain. DO NOT get the 1.5 L. My engine has barely made it over 100,000 I have had $6k of repairs in less than a year. Things keep going wrong now. I had NO issues before. Catalytic converter went out 75-85k miles. My turbo was just replaced. Just beware of this type of engine… every mechanic that worked on it shared this is not uncommon for this type. I would definitely get another terrain but not the 1.5!

Bought it used. The shifter on the dash takes getting used to. But after a month I no longer grab for the shifter arm. Have been happy with comfort. Driving. Gas mileage. Would recommend it.

1/12/26. Just helped my son with a car at Autobhan and had a great experience. Freddy was my salesman and he couldn’t of made the car buying process any easier . Freddy was easy to work with and made it a great experience. Freddy also interacted with my son and my son gained some knowledge as this is his first time. It’s a relaxing atmosphere inside autobahn and I will go back and highly recommend them if you need a vehicle and definitely seek out Freddy!

Our experience at Liberty Subaru was, from start to
Our experience at Liberty Subaru was, from start to finish, quite fine. Our sales consultant, John Clarke was excellent, indeed. He provided thorough explanations of the various features of our new Forester. Thorough, clear and patient--never rushed or pushy. He didn't just explain the car's features; he took us to the car itself and demonstrated some of these features. For example, the connection to the navigation system. This was reassuring, given all the new technology in the 2025 Forester. It is clear that he is very knowledgeable about the car and because of that knowledge, seems to genuinely like it. A lot! He has an even and warm personality. It was such a pleasure to have him introduce us to our new car!

I’ve had the privilege to work with Cesar Marques
I’ve had the privilege to work with Cesar Marques (Service Director) and his customer service support staff on a few different occasions over the last couple years regarding our 2021 Hyundai Santa Fe. Mr. Marques has exceeded our expectations with his excellent customer service experience , his professionalism and his ability to relate to the customers needs. I consider him a major asset to the Hyundai family. If I do decide to purchase another Hyundai down the road, it will be a direct result working with of Mr. Marques. Thank you, Larry Ort
