Used GMC Sierra 1500 trucks for sale near Boulder, CO under $1,000,000

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 !

Chris Whiteside did a fantastic job facilitating my purchase. Chris made it easy and fair to buy this car in a competitive market. I live in Arizona wanted to purchase 2024 Nissan Z. Not only was everyone in my state overcharging. They were all rude and arrogant. As if they were doing my a favor by overcharging for a somewhat limited vehicle. So I bought this car in Colorado. All over the phone. Because Chris always answered my calls and was very respectful. I feel like I made a friend. And believe me, that's hard to say about a car salesman.

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.

Easiest car deal I have ever done. I have and will recommend them to anyone. I will be back the next time I buy another truck. Thank you guys. It was worth the 2 hour drive.

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.

Very good place very nice people would definitely go to them again! Try them out!

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.

After finding a 2013 Mini on Cars.com, I messaged the dealer. They responded quickly. I booked an appointment and met with Tracy. She treated me well, and over the next 2 weeks I decided to buy the car. Though this is a Mazda dealership, they knew the car well. Even better, they told me how I could make my payments to reduce the interest I would pay on the vehicle. This was a real bonus, saving me thousands of dollars during the life of the loan. The day after I drove it home, it broke down. It would not start. I took it back to the dealer and they fixed it straight away. They did not even ask me to do any paperwork. It was a relay that happened to malfunction, and their guy that "talked Mini" fixed it.

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.

Great Experience! I personally never heard of this place until I walked in the lot. I found the exact vehicle I have been looking for for years. The place is so unbelievably clean. If you’re looking for a unique ride for your next vehicle start here. Save your time going elsewhere. Gabe and Stefan were absolutely fantastic! I’ll recommend anyone I know to buy their vehicles here.

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

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.

Wife and I were in the market for a certain kind of vehicle, found exactly what we were looking for at this dealership. They contacted me right away and we ended up purchasing the automobile we needed. The important thing to mention is how extremely polite and professional everyone we dealt with seemed to be. Never once did we feel uncomfortable or pressured, they actually went out of their way to help us get this vehicle at a price we could afford. Our next vehicle will be purchased from this dealership and this wonderful staff!!

I showed up. They had the car outside pulled right up front for me. Cisco greeted me and was friendly all the way through. I drove the car it drives great im a certified mechanic. It is in great condition. I get my tax returns next week. I will be back to buy the car if it's still available l. Based on the way I was treated even if the hyundai is not available which i hope it is but if not I will be back to buy a differnt car from South Creek

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

Overall good experience with the purchase of my truck. Sales department was knowledgeable and accommodating.

I had a great experience as a first time buyer from a dealership and my sales representative was extremely polite and very helpful in helping me purchase a vehicle that I liked.

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.

Carlos at Super Auto was professional, patient, and easy to work with. He addressed my concerns and showed me several cars without being pushy. I appreciated his approach.

After any serving of a vehicle taking it through your car wash before returning to customer. This might encourage more customer loyality. Oil change prices are too expensive. The expertise needed to do that job doesn't equalate to charging that amount.

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!

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

Always a pleasure to get my truck serviced at Mike maroone Chevrolet, gmc, Longmont. Joe was my service advisor and got my truck in and serviced a lot faster then i expected. Service was an awesome. Thank yous

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 inquired about a Camaro Convertible that had just arrived, Pablo replied and actually sug the car our if the snow and did a complete video walk around. Since I live 400 miles.away and this was exactly the car my wife wanted I was excited to have Pablo helping me. I asked him to look into the price and I had one more to call on. I called back the next morning got the price, made an offer. Unfortunately we where to far apart and the other car sold. My bad luck.

Looked at more expensive truck with less options, bought the GMC SIERRA AT4 Turbo Diesel 6. I now only put fuel im once a month. And long distance trips are easier due to better fuel economy. One of my best investments ever.

Jim Albright Is hands down one of the best sales agents I have ever had the chance to work with. No pressure just leads and understanding of my wants and wishes. Was best car buying experience I?ve had to date

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.

Exceptional. Much better than expected. Competent sales staff, and finance. Very fast, no issues. I recommend this Autonation. When another car is needed, I will absolutely look here

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!

Julia was so wonderful to assist me on my first car purchase. We didn't take long.

I needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.
