Happy Customer
I had a very good experience, had a very nice salesman by the name of Branson.B, he helped me out & got me into a vehicle that I like, he was very helpful, & upfront. So I will be recommending family & friends to this Davenport, IA location .
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

We purchased a 2023 GMC Acadia with the assistance of John Thomas, Sales & Leasing /JT and Max in Finance. To start, John made the process painless and easy. He answered every question we had. He was very patient and kind. We had a wonderful experience. Max with Finance was very nice. He also answered all of our questions as well as being patient and kind. Both of these gentlemen provided excellent customer service. You could tell they both enjoyed their job. Thank you so much!

Best Service and Highest Integrity in the Business
After several years of helping me keep my 2013 Tahoe rolling smoothly down the highway; Jay, Randy and the Key Auto Mall Team helped me select my next ride -- a 2023 Yukon XLT AT4. Customer service is first and foremost with this team. I recommend all my friends and family to give them a call. I appreciate their hard work and will continue to bring my vehicle for service because that department rocks too!

Quality of used vehicle was what was advertised.
Quality of used vehicle was what was advertised. Salesman were friendly but one was a little pushy to close the deal. My payment is higher than I originally wanted. All in all I would buy there again.

Worked with JT and Max for the purchase of a 2020 GMC
Worked with JT and Max for the purchase of a 2020 GMC Acadia. We went in with a set monthly payment idea and they worked with us until we got to where we wanted to be. 10/10 customer service experience! Even if things wouldn’t have worked in our favor, we would have left knowing they did everything they could and actually care for their customers! Highly recommend!
