Used GMC cars for sale near Thornton, CO under $800,000

The service was amazing. The people that work there are so nice and will take care of anything you need! If you are looking to by a car or have service done this is the place to go!

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!

Emick's has been servicing our vehicles for many years and has managed to keep them on the road and running well. The Service Dept. is efficient and professional.

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!

I have purchased a few cars from this dealership. Each time they have been fantastic in how they worked with me and treated me. As a result of my experience, I trust when I purchase a vehicle for me or my family, it is done with the best intentions and outcomes. Sean Goodgain took his time to make the encounter personal.

Nice styling,interior has a new design dash which is beautiful and convenient,safety features and cameras are great and easy to used and the active cruise is awesome.

Austin Ellenberg helped us find the exact Buick Enclave that we wanted. He was very nice to work with and patiently helped us understand all the new features on the 2025 car. His explanations of everything were excellent, and we appreciate his offer to talk with us again about any new questions that we come up with. We also appreciate that he had a new battery installed before we took possession of the car, since the previous extreme cold temperatures had run down the battery while the car was on the lot.

Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

Super fast, excellent service. The inspection was thorough, timely and very easy to understand. I would highly recommend the service department at Auto Nation Dodge Ram Broadway.

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.

For my recent service appointment, I was impressed with the excellent communication throughout the process using text messages. Nick was on top of everything from the moment I arrived for my scheduled appointment. Getting a loaner vehicle was quick and easy. After the inspection, I was able to review the recommendations and costs and then approve the services I wanted. The service was completed sooner than I anticipated, and pick-up was a breeze. Many thanks to Nick and the service department for a job well done.

An excellent experience all around. The sales person was fabulous. Now the downsides: (1) From the purchase quote to finance ... like most dealers, a long list of add-ins one would have though were included in the quote; and (2) the car itself has a major, serious issue. I suspect there will be some serious accidents in the future forcing GMC to address the matter.

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.

Jordan is an amazing salesmen who made this process very easy. He is very good at communicating and working to make everyone happy.

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.

Thanks for your service James Hooker. Nice conversation about the sport of Parkour. I've never heard about that before. One word, two words, 25 words.

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.

DJ was my salesman and he did an amazing job! I highly recommend going to Alpine Buick. The Facility is beautifully represented. Always eager to help.

Brandon West worked with us for the purchase of a 2021 Kona EV. He was very accomodating and professional about addressing any of our issues and has followed up several times after the purchase to make sure we are happy. He is very responsive to our follow up questions. We have found that the Kona EV is a perfect little car for running aorund town at a cost of around 2.5 cents a mile if one is buying electricity at $0.12/kWh. It sure drives like a little rocket compared out our other IC car

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.

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 have enjoyed my vehicle. It is comfortable and drives very well. I like the color also. It is very roomy, takes off fast and the safety features are very beneficial.

Great Service writer. Chris was prompt and helpful. I like the attention to the details and listening to all the concerns. Thanks for a great experience.

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

Good communication, easy to schedule a time to see the car, low pressure - not the typical dealer experience!

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. ??????????????????????????????????????????? ?????????????

I went in for a test drive. I’d called ahead and the vehicle (CR-V hybrid) was pulled up front and ready to go. A quick interaction with the manager and the salesman (which may have gone faster because I was already in their system from a prior visit) and we were off on a good test route. The salesman, Sasha, was knowledgeable about his product and easy to converse with, and asked good questions to get a feel for what I was looking for. No hard sell. If all dealership interactions were this efficient, effective and pleasant people would feel more positively toward dealership relationships.

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

Great experience, happy with everything... Great service, friendly staff, great facility...very happy with a car... I will definitely recommend this dealership to all my friends and relatives...keep a good job...

I bought this 2017 Tahoe w LT trim new. Have 60K on it now and have had no issues with it. We are not towing with it or doing high speed racing so we find the 5.3L Motor is smooth and quiet (and have not had any lifter issues which others have reported). Transmission and suspension also smooth. We keep Michelins on all our vehicles and have found this Tahoe very quiet and comfortable for road trips with 4-6 people and luggage. The LT trim pkg deleted some comfort items I wish I had (like heated steering wheel) but it still is pretty much leather-and-loaded so it was a good value at the time. I have had Suburbans for 35yrs before purchasing this Tahoe and I will probably go back to a Suburban for the extra cargo space when I trade this Tahoe in. But this has been a nice and reliable vehicle for us. No complaints.

Guys were great, no hassles! Tito was right on top of things. Car is fantastic!!!

We drove two states over to McKenzie Buick GMC in Milton, FL to meet with Nick and make a purchase on our new Yukon Denali. Customer service was top notch. We were going for their 2019 Yukon Denali to replace a 2008 Tahoe LTZ. We are very pleased with the vehicle. The upgrades are wonderful. Love the cooling seats, the wifi, the HUD and even days after our purchase they have reached out to check on how we were and mailed us a small gift that meant so much. We will definitely use them again if they ever have what we’re looking for on a future purchase. - Brandon Howell 2019 Yukon Denali

Chen Liang is an excellent sales rep and made the buying process easy! Similarly, Johnathan Creighton was excellent as well for the financing process! Excellent staff at this dealership who helped walk me through every step of the buying and loan process as a first time car buyer. 10/10

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.

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

I been buying cars for over 15 years and this is the best place I ever been thank you so much to jay the manager and Ryan . Jay the manager give me a very good treat even on my work clothes very respectful person.

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!
