Mike Hawkes and his service department team are outstanding. Not only did they go the extra mile to fix an issue with a used car purchased from the dealership (not a GMC), but the level of communication, attention to detail and timeliness were amazingly good. Thank you.

We've had a great experience with Key Auto Mall GMC
We've had a great experience with Key Auto Mall GMC purchasing our new 2025 Acadia. Brian MacGee was wonderful to work with along with General Manager Theron Maring and all the other great staff. Brian especially has spent a lot of time going over all we need to know about how this car works and has several times answered more questions since we purchased the car a week ago. He helped us purchase new cargo mats and get the protective coatings on the car, inside and out. Brian has been professional, friendly, and so helpful to us. We highly recommend Brian and the Key Auto Mall GMC team and will definitely consider them for our next auto purchase.

I called the sales department at 7 am.
I called the sales department at 7 am. Was greeted by Emma. Confirmed the truck I wanted to look at was available. Upon arrival I was not overwhelmed by a salesman in the lot. Excellent. Once I went inside I was promptly greeted by Emma who remembered me calling and immediately had the truck I wanted to see ready for my inspection. Very professional young lady and very down to earth. Next I was greeted by Dean in sales who was a great guy. No pressure whatsoever from him. Tested the truck. Asked for a price. Got it ASAP with no xx. Great guy. Deans attitude and honesty sold me. Haven’t been in a dealership like this before. Honest real people. Not the fake people trying to get your money. I was next introduced to any in finance and she was very professional and very pleasant. Just wish I got to meet her dogs. Overall best experience buying a vehicle I have ever had. They have my business. Can’t go wrong hear. Thanks GMC team.
