Drew was there from our first call until we went home
Drew was there from our first call until we went home with a new Chevy. He worked hard to get us where we needed to be financially. Explained everything we needed to know about the vehicle we purchased. Drew was also there for some follow up calls, very patient and kind. We will definitely return for our next vehicle

I live in Utah but recently bought an Escalade from
I live in Utah but recently bought an Escalade from Halladay Cadillac in Cheyenne and honestly, I was just super impressed with everyone. You can tell these guys know how to treat people right and run a solid, honest dealership. They picked me up at the Denver airport and drove me up to Cheyenne. After the sale, on my way home I noticed that the USB and HDMI ports in the vehicle did not work. It was unexpected, but the way they handled it really meant a lot. The repair wasn't cheap but they didn’t make excuses, they just took care of it and made things right. That kind of service is rare, and it meant a lot. It was clear they stood behind what they sold, and that goes a long way. I’d absolutely buy from them again and recommend them to anyone who wants to work with good people who actually care about doing the right thing. Special thanks to Bryon the salesman who was super helpful and never pushy and John the sales manager who was a pleasure to work with in getting the issue resolved after the purchase and Shawn Smith the GM for standing behind the sale and being willing to take care of it. If I could give more than 5 stars I would.

I went into Corwin looking for a specific vehicle. Bailey Reed approached me and I told him I was interested in a truck on the lot. He went the extra mile for us to get what we wanted. He made it easy for us, I appreciate him a lot, he did a good job for my wife and I. This is the second time we’ve bought vehicles at Corwin, it’s our go to place for an honest deal.

Went to just look at new cars, Wrong idea!
Went to just look at new cars, Wrong idea! We met Dexter and he was the best car salesman I’ve ever dealt with. He wasn’t pushy, He let us look, and then he gave us a few cars to look at at what he thought we would like. Found a car in a matter of an hour. Went back the next day and boom it was ours. They had the fastest and the best system at purchasing a car, simple and easy no more back-and-fort smooth and easy and I would recommend Them hands down.

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.

My business truck, in very cold weather, had a momentary maintenance code. While she was in for the code, I requested a service be done on the drive train, ie. tranx, diffs, and txfr case. Service representative Sonya got me in and out, back on my schedule, out of town, right on time. Her performance was exceptional, as was all of the aspects of my service with Laura GMC in Sullivan Mo!!!!
