Used GMC Sierra 1500 AT4 for sale near Fairmount, CO

Josh (Service) did a great job. Helped with everything I needed looked over and he was able to transport me back and forth. This was helpful and convenient. Instead of being stuck at dealership with lots of people.

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.

It was a smooth and straightforward transaction with sales rep, Shaun Benipayo. He’s genuine, warm, and very easy to work with. He was accommodating throughout the process and demonstrated strong knowledge of the product. He answered every question clearly and made sure we felt informed and confident. He also took the time to show us different options, which we really appreciated. Nick Kramer gave us time to think of what plan we would get without pressuring us or whatsoever and . Overall, a great experience.

Any reviews on this vehicle is not correct. We are first owners and it’s been an excellent truck. We hate to see it go !

We found a car we liked online and went and looked. We were able to take the car for a test drive, the price matched what we had in mind, so we bought it. We had pre-approved financing through USAA, so that made it even easier. We'll be back.

Easy purchase experience, would recommend to anyone looking for a new car. Everyone there was friendly and made the whole process as smooth as possible

Professional from the start and they were not as much pressure as so many other dealers.

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.

I had Ally (financial manager) and Byron (sales) as the people who helped me work out a deal. They were very respectful and so so helpful with getting me the best deal possible. I would highly recommend you go to them if you can! Usually when I go into a dealership I feel very hostile, but this is the first pair of dealers that I felt calm and very open to talk to. Talking to them about the car was one thing, but also talking to them as normal people was a plus! Thank you guys for such a great experience and helping me get the car that I wanted!

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!

Thank you Josh for coming to my house and replacing my windshield. On time and under and hour. Great work and much appreciated.

Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Easy to work with, set everything up in a timely manner. Mathew did great explaining all my options. When it went to finance Juan was very knowledgeable and straightforward. Also a bonus is most of the documents are digital now.

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

Austin was a great help through the whole process and made everything run fluid and smooth. Treated my car like it was his own or a car he was buying. It was almost like he was buying it with me.

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

Our salesman, Ed was great. Patient, funny and knowledgeable. Only showed us the cars we were interested in . We would definitely work with him again.

I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

Had the great experience working with Cornell! He’s so knowledgeable and did a fantastic job working with us!

This truck has a jerk when changing gears sometimes. I enjoy the truck overall easy to handle and comfortable. Drive with ease sight is good when driving.

We bought 2 trucks from them. Great relationship with them and easy to work with. Customer service is great. They even helped us with a major repair. Dan the owner and his staff really care about their customers. Highly recommend. I won’t go anywhere else

I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Jesus Hernandez was amazing and helped with us get into a vehicle same day woo!

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. :)

Just a update regarding my last rating and review, after a meeting with the owner Ali Awada. He took care of me and paid for my car repair and gave me 100.00 for my family and I to have dinner. Thanks Colorado Auto Finders for doing your best to make things right for with me.

2021 GMC sierra 1500, 5.3, crew cab 4x4, 21000 miles. brakepad monitor lites up. dealership says needs brakes and rotors in back. one mo. on warranty. our rural roads dirty up the monitor. Needs new monitor. brakes look great to me. No noises. dealer says parts on order GM strike. Can't replace myself cause of computer...

excellent bought a good car good prices 100% recommended Fatima nuñez the best group 🙏🏻

My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Isiah, Arie, and the rest of the team did a great job making our car buying/trade-in experience go as smoothly and quickly as possible. They even made sure our car was detailed and had a full tank of gas before we left the lot! Great communication from start to finish.

2024 GMC sierra 1500 duramax 3.0 is great truck. Great ride and great MPG. 100% recommend to any prospective buyer. Love the truck and how it perform.

AutoNation Subaru Arapahoe provided an outstanding car buying experience. The salesman Andrew that helped me was extremely patient and educated me along the way so that I could make the best decision for me. I walked away with the perfect car and I absolutely love it. I couldn’t be happier and would recommend this dealership to anyone who’s looking for a new car. Great business full of great people.

This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

Great performance, hard to clean, everything, I expected. Getting lots of compliments and head turning. Stomping with thee BIG DAWGS!!!! Good gas mileage on highway.

Elba me atendió muy bien! Encantados con el servicio, muy bien todo el proceso súper rapido

I truly enjoy every aspect of this vehicle except for the fact that to have my text messages displayed on the screen I have to use a cord and cord my phone into the vehicle. I can Bluetooth phone calls But I cannot get any messages to display without using a cord. For the truck being a 2019 and the price point of it that is absolutely absurd. Other radios that GMCsells has this feature. This truck does not.

Saw a preview of a Porsche Macan GTS they listed but they did not have photos posted so I inquired. David emailed me immediately, and told me it was incoming and would send pix as soon as it arrived. A day or 2 later I got several high quality photos of it inside and out and a follow up phone call making sure I received them, and if there was anything else I wanted photos of or had any questions. Vehicle was beautiful and professionally detailed, but unfortunately when we went over the option list it was missing a few "must-haves" for me. When I told him that I wasn't interested only because it didn't have those options, he asked if I would like him to keep my info and let me know if he finds the exact one I'm looking for, which I really appreciated! Other dealers with similar vehicles I inquired about took days to reply and immediately lost interest in making a sale as soon as we determined their vehicle was missing those must-have options. At that point, they were only interested in making the sale on THAT car TODAY, not a potential future sale. David understood that not all deals happen immediately, and I'm a serious buyer just waiting for the perfect optioned car, so I'm really hoping he is able to find me the exact spec GTS I'm searching for. I know it's out there and with the excellent sales experience so far, I feel comfortable buying a car from them.

It met all of my needs, it drives well and is easy to maneuver for its size. I would recommend this vehicle for anybody who needs a full-size vehicle.
