2019 Sierra SLT X31
I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

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.

Great truck to own.
Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

They lived up to their name!!!
I usually write reviews when I absolutely hate something, but this time I really wanted to let everyone know how AWESOME this place is! So here it goes... I was in need for a new car and needed it fast. I was very limited on money with it being so close to Christmas. I stopped by several other car lots around town and all they wanted to do was get me into something that I would have to finance through them at a ridiculously high interest rate. I was getting pretty discouraged and was beginning to think that this was going to be my only option until I stopped into this lot. I explained my situation to them and Matt was so accommodating and helpful. He listened to me and stuck within my price range instead of trying to get me into something more expensive like everyone else did. Their prices and mileages also seemed lower from all the other lots I had been to. Matt let me take one of cars I was considering for a few days which wasn't even a possibility with the other lots even with my down payment! What impressed me the most was that Matt and Mark went the extra step above and to my very pleasant surprise found me, not 1 but 2, of the cars I really wanted!!! Who actually does that anymore? I can positively tell you that none of the other place I went to did! I am now a very happy owner of a 2010 Lincoln MKS thanks to Matt and Mark!!!

Excellent riding quiet car with double DVD screens for the kiddo's. Plenty of power to pass and the safety features like adaptive cruise yield a well rounded vehicle.

Awesome Dealership Excellent Staff
We drove 2 1/2 hours one way to a dealership we had never seen, not knowing what to expect. Immediately upon arrival, we saw that the cars were professionally displayed and that the facility was clean and orderly. The owner met us himself and introduced us to the salesman and showed us the car we were looking for. We purchased a Jaguar Vanden Plas that is a super vehicle and received the best treatment we have ever experienced at a car dealership, no pressure and the desire to have our experience pleasurable. Thank you !!!!
First time to own a GMC and I am very impressed
This car was exactly what we were looking for, and for a used car, it was in excellent condition. First time owning a GMC and will definitely consider a GMC next time we purchase.

My wife and I met Dave who was really great to work with. He explained key features of the vehicles and had great information as well. The process was really easy. No hassle, and most of all they gave us a great deal for our trade-in and the prices are competitive. Will be going back again for our next vehicle.

I always bought the GMC Acadia (4 times) but decided to try the terrain. I absolutely love it and it's a great car for zipping around in town. I would take it for a weekend trip but not on a long trip as it doesn't have a lot of cab room, but for two people it is fine

So far I have been enjoying my 2025 GMC Canyon Denali. It has a great ride and is very comfortable. The Canyon drives very nicely and has plenty of power for my usage (I don't tow anything). It tracks well and has a very smooth ride that rivals previous BMWs (328 and X5's). I have had zero issues but the vehicle is only 1.5 months old (approx 1,700 miles on it). THe only downside (which many people agree on) is that it is seriously lacking storage space. Center console storage is about 1/2 what it was in my 2020 Jeep Wrangler and under seat storage (rear seats) is almost useless ..very little space. That being said, I'd still recommend the GMC Canyon and hope it continues to impress me.

Justin was nice and easy to deal with. No high pressure sales. Paperwork went quick. They had a good selection of cars. No air in one building but they had fans

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.
