Great Buying Experience
Look for Lindsay she made buying hassle free after a long day at work. Once I was in finance Leonel had the paperwork ready and it only took a few minutes to complete the sale.

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.

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

Nicholas Nichols was a great salesman and helped me find the perfect car. Ryan Griep was a terrific finance guy and made the financing process super easy.
This is an attractive and enjoyable vehicle.
I traded my Chevrolet Silverado for this GM Certified GMC Sierra 1500. It is an attractive and enjoyable vehicle. Some years ago I had a GMC and really prefer them over a Chevrolet. This vehicle is just what I need for hauling and general driving.

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

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.

I own a 2023 Sierra 1500 Elevation equipped with the 2.
I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

Failed transmission and full replacement
We have owned our GMC Sierra 1500 for approximately 9 years now. The only real disappointment with the vehicle is that we had to have a full transmission replacement Just after the 100k mile without any warning whatsoever. The truck now has 107k miles on it and now , again out of nowhere, we are experiencing slipping in the trans and the engine light is now flashing. Very disappointing since we are starting to feel uncertain about the reliability of the vehicle now. The truck itself is gorgeous and shows ZERO signs of its age, sporting new rims and tires and a lifted body and no rust on the body at all. We hope there are no major issues with the engine as the vehicle has always been maintained as needed and on time for regular servicing at the dealership.

My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

I was interested in a new GMC Acadia, specific features and model. Zac Taylor worked very hard to bring a vehicle from the Colorado Springs store. He had everything outfitted as needed, worked out details remotely, then delivered it to me in the mountains. I drove away a great new vehicle at an outstanding price point. Thank you Zac for all of your hard work during this car purchase!
Like the truck but also disappointed
Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

We had a great experience with this dealership!
We had a great experience with this dealership! I highly recommend using Jeremy Tabangay as your salesman. He was very polite, and wasn't aggressive in his sales tactics. He really made you feel like you weren't just a number to him. He also did a follow up after we purchased, just to make sure that everything was going well. I would also like to give Matt (finance department) a good review. He was fun to work with on the financing of our vehicle, and didn't pressure us into buying any add ons. He was also very quick in getting all the paper work filled out. We really enjoyed our entire visit there. I would use this dealership again in the future. Especially, if I was working with both of them.

It is a great truck with great capabilities! although i must say, some of the technology in this car has its low points. Center stack tends to not cooperate during bluetooth pairing and the headlights have poor illumination to the point i had to retrofit LED bulbs for better visibility.
