Great experience!
Great experience! Chris Lambert was my salesman he was very helpful and went over all the features of my new car. Financing was quick and efficient

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

Marc D is the Man!!
OMG!! I’m so in love with my new vehicle & Marc Darnell is absolutely the Best!! He worked & worked until I got the car & price that I wanted..(And trust me I gave him a Task!) And Mr. Chris topped it all off with a special holiday surprise 😆 I love it here!! Go see them!!

I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

Everyone was very helpful and kind.
Everyone was very helpful and kind. I requested scratch repairs on my purchase and it was completely taken care of as discussed. Salesman was very nice and no pressure!
I have the 1500 double cab with standard bed.
I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

Jon A was a gem to work with.
Jon A was a gem to work with. He bent over backwards to find deal/price that suited me. He drove my car home that evening, so I didn’t have to find someone who could meet me at the lot later in the week. He researched and finally bought a charging cord for my new, leased EV (didn’t COME with a cord!! What’s up with that, Kia??). Couldn’t have been nicer and more helpful.

Justin Hart is a great guy.
Justin Hart is a great guy. He made the experience as painless and enjoyable as possible. Most fun I've had buying a truck. He showed me all the features of my new vehicle and on the paperwork, he explained thoroughly about what I was signing and made sure all my questions were answered. Great guy and great service. I would recommend seeing Justin Hart at John Holt Chickasha to anyone who is looking for a new car.

I had an excellent experience at this dealership!
I had an excellent experience at this dealership! Though it took a few hours, which buying a car normally will, my sales person, Evans, made sure that I had snacks and water if I needed them. As a first time buyer, they helped me through the process and got me the best deal. I was able to go home with a brand new car! They explain everything so well. Special shoutout to Evans, he did a great job and was very helpful! I definitely recommend!
