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!
