Used GMC Sierra 1500 SLT for sale near Mountain View, CO

Best experience I’ve ever had, Nelson was awesome, super knowledgeable and a very honest kind person got to meet Paul the Gm and he was also extremely helpful and nice. Thank you

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.

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.

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 had an absolutely exceptional experience with AutoNation Toyota, and I cannot recommend them enough! Purchasing a vehicle can often feel stressful, but this team made the entire process seamless, efficient, and genuinely enjoyable. David Butkovich, my salesperson, was phenomenal from start to finish. He was knowledgeable, patient, and never once made me feel pressured. David took the time to truly listen to what I was looking for, answered every question thoroughly, and ensured I felt confident throughout the entire process. His professionalism and friendly approach made a huge difference in what can sometimes be an overwhelming decision. Rajh in finance was equally impressive. He made what is typically the most frustrating part of buying a vehicle feel simple and straightforward. He explained everything clearly, worked efficiently, and made sure I was comfortable with every step before moving forward. His transparency and expertise gave me complete peace of mind. After recently dealing with the stress of losing my previous vehicle, the care, compassion, and top-tier customer service I received from this team meant more than I can express. Driving away in my Jeep Gladiator was an exciting moment, and it was made even better knowing I had such a supportive team behind the purchase. If you?re looking for a dealership that values integrity, professionalism, and truly outstanding customer service, AutoNation Toyota is the place to go. Thank you to David, Rajh, and the entire team for making this one of the best car-buying experiences I?ve ever had!

Great truck, solid engine, comfortable, smooth, and it handles great for such a large vehicle. Get one and enjoy miles of roadtrips with all you can tow or haul.

Great service and love my car! Very professional and helpful in selection and all the paper work!

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 !

Awesome prices, awesome staff, everybody was friendly and very helpful, was not rushed or pressured

handles and drives great, the electronics don't always work, mirrors don't always work, spray with wd 40, check engine light, EVAP culprit, auto nation has no luck with this, will drive it till the warrenty expires and its back to ford for me

Sergio was very helpful! Good cars at good prices. Would definitely recommend buying a truck here.

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.

I took delivery of my 2026 Suburban Z71 (6.2L, custom Borla exhaust, red tintcoat) from John Elway Chevrolet on 23 October 2025, and I can say without hesitation that this was one of the best vehicle purchase experiences I?ve ever had. My journey with this dealership started way back in July 2025, when I first tried to buy a similar vehicle. That original deal didn?t work out, but Trevor (Internet Sales Manager) never dropped the ball. He stayed in touch, helped me custom-build the exact Suburban I wanted, and kept every promise, from the guaranteed price to a very fair-trade value on a challenging trade. Throughout the entire process, Trevor?s communication, communication, communication made all the difference. He kept me updated at every step as the vehicle moved through production and delivery. On delivery day, I met Amanda, who made what could have been an overwhelming tech setup feel effortless. She walked me through every performance and technology feature, connected my OnStar account, synced Apple CarPlay, and ensured I understood all the apps and settings before driving off the lot. Her professionalism and enthusiasm turned the delivery into a great experience. Daniel (F&I Manager) was equally professional, direct and knowledgeable when discussing warranty options, but respectful when I declined. The entire process was efficient, transparent, and team-oriented, which I deeply appreciate as a former military officer who values teamwork and integrity. When I left the dealership, my new Suburban was spotless, fully set up, and ready for a long drive south to Texas. I?ve bought many vehicles in my life, and I usually ask dealers not to put their decal on the back. This time, though, I left the Elway football logo right where it belongs. It?s a reminder of a team that truly earned my trust and my business. I not only recommend this team, would actively seek them out again in the future. Trevor, Amanda, Daniel.....a true pleasure to meet you all and thank you for a great experience. I hope to see you again in the not too distant future.

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...

Great experience buying my Tahoe from Greenwood. JS made sure my first time experience with them went exceptionally well. I highly recommend GWA for all your automotive priorities.👍

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.

My family and I went in looking for a nice cars for our son who needed his first car and we were blown away by the experience. The second we walked in they treated us like family and helped us find the perfect vehicle. We will be coming back in the future!

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.

We purchased our vehicle from Berkenkotter Motors and we couldn't be happier. We came from Brush in search of a 4 runner and the experience was well worth the trip. Lucas and Dan were very honest, helpful and treated us with respect. They were easy to work with and made us comfortable with our purchase. They made the buying process stress-free and they ensured everything was handled smoothly. I highly recommend them. Thank you so much guys! We definitely recommend your dealership and look forward to working with you more in the future!

I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

Helpful and kind, answered all my questions. Next time I'm shopping for a car, I will come to Luis. It's important for me to have someone I feel listens to what I need.

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. Overall very comfortable ride and smooth drive

Great dealership top to bottom. Bought my truck there almost 4 years ago, I bring it back in regularly for preventative maintenance. Absolutely phenomenal service, work with Ian, he is the best service advisor

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. :)

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!

We have bought 3 cars from andrew and he coworker. These two are the best around. They take good care of their automobile’s and their buyers. We always go to them first and we will for a long while to come.

Good afternoon everyone, yes, I’m a lady and I’m an owner of a 2017 GMC Sierra 1500 Denali, it has a V8 motor fully loaded sunroof & also it has heated seats & steering wheel for the cold winter months & in those hot summer months you have A/C seats nothing better than that am I correct? It’s been times like that wouldnt trade for the world!! So for all you ladies who think BIG TRUCKS are just for men, go out there & buy one have them put on some electronic slide in/out rails & go out & show the shows the boss!! lol 😄 I’m out looking for a new one now either a 2500/3500 pearl white

My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.

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.

The truck has more features than I need. It is quiet and comfortable. it has plenty of power to pull a work trailer. Overall a nice truck

We had an excellent experience working with Dan & Wade on the purchase of our new vehicle. The sales team helped us through the process and were incredibly patient. Used vehicle prices are out of control and it's comforting to know there are car dealers that go the extra mile. I would rate our buying experience 10/10. We will be back when looking for another vehicle. Give them an opportunity to earn your business!

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.

Helped a friend pick out and buy a truck at Red’s Auto & Truck. We worked with Rick Hawkins and he was refreshingly knowledgeable, professional, and polite.

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

James at in the service department went out of his way when an appointment I had was accidentally cancelled online. He noticed, checked in, and got my service rescheduled immediately. He provided multiple tire options and a competitive price. The tire process is much faster here than others Ive used and they offered a dropoff if I wanted to go home.

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.

Very good experience with O’meara VW buying a nice used Jetta. Quick fast deal without the usual back and forth time consuming runaround. Friendly courtesy call a couple days after to check on us. Thanks Karson, Elva and sales manager Steve. 👍👍

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
