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

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

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.

Amazing experience .super patient and no hassle team, completely transparent Charles and Rick took good care of us! I would go back there again with my next purchase

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.

Rafael H was very attentive to what we were looking for in a clean used diesel p up . His assistance in our purchase with our purchase was very good . professional, not pushy Gerald & Kay Schreiber

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...

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

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.

Excellent delivery of my new car. I love their new hybrid. would choose to buy a new car from them again.. the GM Mark was excellent

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!

The team here went well above the expectations we had. I cannot recommend a better place to get a car! Jimmy and the whole staff were amazing, professional, upfront, courteous and everything you would want and expect from a car dealership and its employees! Top notch for sure!

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.

Lazarus was great to work with and got me a great deal. He was very professional. The people there were friendly. It was a very quick process.

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 experience Diana helped me out a lot had an easy first time buyer experience drove of with what I wanted thank you Diana and Ethio Motors.

This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

Our two Mazdas were total losses due to the Hailstorm that struck Cheyenne WY on August 1, 2025. I found AutoSearch USA through cars.com and contacted them about a Mazda CX-5 the had listed. Mike Blunn was great! They had just listed the car the previous Friday, and still needed top get some prep work done, but we set up a date to see it the following Tuesday. The car was not quite ready for us to take that day, so we made arrangements to meet at an Enterprise location midway between Cheyenne WY and AutoSeach USA's location so we could finalize the sale and turn in our rental. Everything went off without a hitch. I highly recommended AutoSearch USA for anyone looking for quality car buying 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 !

I recently purchased a truck from SAG Denver, I have had a very positive and professional experience with the sales and service departments. I normally avoid dealerships at all costs, however I came across a beautiful truck that I was having difficulty finding on the private market. I enquired online and was replied to very expediently. I received a no pressure call from a sales person who scheduled an appointment with me. When I arrived, I was greeted and assisted immediately. I test drove the truck with Tracey, who by the way, I highly recommend working with. After driving and inspecting the truck for a bit, I detected what is a common mechanical problem with that type of truck. I brought it up to Tracey and the sales manager Dan and my concerns were immediately acknowledged and validated. Dan did not try to gloss over my concern or argue that there was an issue, instead, he gracefully offered to have the repairs made along with any other contributing or resulting damage as needed. I left the truck with them to begin the repairs, unfortunately it was a bit more involved than originally thought. There ended up being a significant amount of engine work needed, nothing that could have possibly been detectable without opening up the motor. I think most dealerships would have somehow tried to find a way to charge me or unwind the deal rather than proceed with completing all necessary repairs and making the truck run properly. I have several other vehicles so I wasn't by any means inconvenienced, however I did purchase the truck because I had to haul some things for family. After the repairs ran into an extended period of time I did email to express my concerns, I received a call from Dan offering me another truck from their inventory until the repairs were completed on mine. I can't express enough how impressed and pleased I am with the entire experience with Springs Automotive in Denver, I would definitely recommend them and would buy from them again.

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

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

They were fair and responsive. Answered all questions. Speed of buying experience was best I’ve ever experienced.

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!

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

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.

Megi has helped us into three vehicles over the past year, and every experience has been efficient, seamless, and genuinely enjoyable. She’s not only incredibly knowledgeable and responsive but also an absolute pleasure to work with. Megi goes above and beyond to make the process smooth from start to finish. We highly recommend her as both a person and a trusted partner when you’re looking for your next vehicle!

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.

Overall we had a great experience at this dealership. Good communication and customer service from Sevan. We believe we found a great car for the price!

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.

We worked with Leon and Aaron(finance), got what we wanted. They were great! Highly recommend. Thank you!

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.

Everyone from the sales rep., sales manager, finance manager and shop team worked to make my experience simple and left a lasting impression. I will absolutely recommend this dealership to anyone in the market for a vehicle.

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.

?????????? I had a great car-buying experience at Mike Maroone GMC in Boulder. From start to finish, the team went above and beyond. A special thank you to Austin, the new car sales manager, Brayden, Cosmin, and Alec. Their customer service was outstanding, and what really stood out was their follow-through. Anytime I had multiple questions, they took the time to explain things in a way that I could clearly understand?never rushed, never brushed off. This wasn?t just about buying a vehicle?it was about feeling taken care of. The level of professionalism, patience, and genuine care made this the smoothest and most enjoyable car-buying experience I?ve ever had. I highly recommend Austin, Brayden, Alec and Cosmin, and the entire team at Mike Maroone GMC Boulder!

Thorton Location/ They were undestaffed but did a great job helping all clients did not close until finished. Kelly was our saleman, well knowledged and answered all our questions. David our finance rep did a great job about getting us the best deal. I would refer family and friends.

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.

I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.
