Used GMC Sierra 1500 trucks for sale near Glendale, CO under $800,000

The experience of buying this Dodge ram truck from this dealership was exceptional! The dealership was courteous, professional, attentive, and kind. It was a really great experience!

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!

Fantastic people, the process was so easy and stress free…I just stopped by on a Saturday over the 4th of July weekend just to look at a Hummer ev (I planned on Buying another Hummer I found online) and I left the dealership 3 hours later with a new car and new friends…I dealt with Charlie and Ryan, from the second I stepped on property and met the guys for the first time I felt like I had know them for years…I am a great judge of Character and there easy going positive personalities where very genuine and so authentic, it made me and my wife feel as if we where dealing with a good friend or family member that had our best interests in mind. From start to finish and even 3 months later I am still feeling the warmth from them. I will never buy another car from another dealership as long as Ryan and Charlie are there…AutoNation is Lucky to have them on there team and I am reminded of my experience every day I get into my new Hummer EV and I will continue to pass the good word on to everyone I encounter!!! Thanks Alpine Buick GMC

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

Got an oil change and tire rotation done. Todd was excellent assisting me. A stud was broken while rotating the tires but they took care of it.

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!

Maya was very helpful and she did everything that she said she would do before I bought the car really like this dealership everyone was so helpful

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.

Outstanding customer service / warranty service / repair service. Steve, Kevin, and the technicians came through again with a warranty repair in record time. I am very glad I bought an extended warranty to match my lease term, but it would be nothing without the service team here at AutoNation Jeep in Golden. A steering part failed on I25, and we experienced significant ?death wobble? (IYKYK). Steve responded to my text immediately and I went in two days later (my schedule). The whole repair was done in less than 3 hours, and I was on my way. The service department here continues to earn my loyalty each and every time I come in. They are fast, friendly, professional, and demonstrate a genuine concern for me and my Wrangler. Good customer service and good vehicle repair service are hard to find. Both are top tier at this location. Again, it is worth the half-hour drive from our house and more. Thank you from a very satisfied customer!

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.

Best ford dealership! Team is smart, kind and fast. Had a great experience working with them and even with a small issue with my new car is was fixed and I could not be more excited with my new explorer. Thank you AutoNation Ford Littleton!

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.

Our salesman Eissa Hizhley, was a pleasure working with, he got us exactly what we wanted. Finance Deptment was easy to work with. We will go back again.

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

Had a great experience trading in my 4runner and getting a new tundra with Chris Williams yesterday! Couldn’t have made the process easier from start to finish and appreciate them staying late for us.

Does anybody else’s truck just sit there after you put it drive? I have to bump the accelerator to have it go into gear. ??????????????????????????????????????????? ?????????????

Tony Rocha is one of the finest and diligent salespersons I have ever worked with. He responded to my Cars.com evening inquiry the very next morning before the dealership was open. Still waiting on other dealerships to respond from a week ago. I purchased a new Z4 M40i and Tony stayed with the transaction until the car was loaded on a carrier. If you go to Schomp BMW be sure to ask for Tony!

Excellent comfort and very good truck, it is very functional in every way, both for business and for personal, it can be said that I have the 2.7L Turbo engine and I can move up to 11500Lbs already checked by me

Have only dealt with Rayce. He is incredibly attentive to detail (even those I forget). Found his honesty and knowledge to have been so very helpful in my purchase choice. Will continue to return

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

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

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!

?????????? 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!

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.

Everyone at this dealership is a class act! Great service. Ask for Ed Rivas to be your lead salesman. He will treat you right and take care of your needs. Extremely knowledgeable and responsive!

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.

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.

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.

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

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

The dealership responded quickly and were knowledgeable about the vehicle I was interested in. They also maintained contact even though I didn’t purchase that particular car.

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.

Great Company, had exactly what I was looking for would recommend! Fast, friendly, and professional.

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.

I really appreciated the free service for my first time in with our new car.

I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

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