Used GMC cars for sale near Thornton, CO under $1,800,000

Jillian Tran provided friendly service and helped keep me informed of getting the used car fixed before buying it. And it passed the pre purchase inspection well. Schompf didn't pressure into buying anything but spent the time to do good.

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 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.

The Yukon checked all of my needs, I have plenty of room for my children and my Great Danes. I enjoy driving the Yukon and how it handles, overall love this vehicle!

Our experience with Jason Montgomery was absolutely fantastic! From the very beginning of our car search, Jason went above and beyond to help us find the perfect vehicle. He was incredibly patient, knowledgeable, and genuinely cared about making sure we found exactly what we wanted. When it came time to go over our new truck, Jason took the time to explain every feature in detail ? making sure we understood how everything worked and felt completely comfortable before we drove off the lot. His professionalism, friendliness, and thoroughness truly made the whole process easy and enjoyable. We couldn?t be happier with our new truck or the amazing service we received from Jason. If you?re looking for someone who truly goes the extra mile, Jason Montgomery is the person to see!

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!

Andy Carney was professional, respectful and patient.He listened to my concerns and wanted to understand the features I needed in a new car. He worked diligently to make sure the car I picked was the right one for me. He took the time to show me all of the functions and even set up many of the basic choices. He made sure I felt comfortable driving the vehicle and using the technology. I certainly recommend Andy as the sales person to buy your next car from!

Just trade in my 2015 GMC Denali with 140000 miles on it and still holding strong at trade in best SUV I ever had upgraded to the new 2021 Denali and boy do I love this SUV from comfort to outside design just an amazing new well designed SUV.

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

We love our new Yukon thanks for all your help!! Very fast, and helpful staff, appreciate everything!!! Carolina was very nice and very helpful and made our buying experience amazing!!

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

Was looking for a 2025 GMC Acadia Denali. Went to AutoNation and was met by Caden Noar. He was fantastic! Showed us the Acadia he had on the lot, gave us a test ride and answered all our questions. Not once, did he pressure us to buy but was more interested in answering our questions. After the test drive, we noticed a Buick Enclave Avenir in the lot as we were exiting the dealership. Liked the car looks and went back into the dealership to see if Caden was available to show us the car. We knew nothing about the car. He came out, gave us a test drive, answered our questions and then asked us if we would like to see another feature of the car, so out we went for another drive. Again, no pressure to buy and we parted. Over the weekend, we decided we really loved the car and called Caden on Monday to see if we could discuss the price and terms. Bottom line, we bought the car at the price we wanted. Outstanding service from Caden to the Sales Manager to the Contract/Finance Team!

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

if you’re looking for easy prices buying a car definitely ask for Vlad. He’s the best and very professional. Thanks Toyota you number one!!!

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!

Absolutely awesome, my jeep had an issue with rear differential, they looked at, ordered the parts and fixed it. No xx no problems just let’s get it fixed. They even started a star case because the entire carrier was damaged. Team, awesome exemplary and utmost professionalism in action. Huge thank you to everyone that stepped up and got my jeep fixed.

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.

Staff very friendly and efficient. Jordan very was helpful. This was a good buying e,perience

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.

Great service, Adam at the service Deparment was very profecional explaining everything to me quick response to get the truck schedulefor service. very satisfied with auto nation broadway.

Excellent and reliable, only thing buyers have to do is buy a AFM disabler that you can stick into OBD2 port to avoid lifter failure (longer story, nobody wants a V8 to run in V4)

Awesome experience. The five star rating is too low, I'd give them a 15 star. No high pressure sales. Everyone was so nice and helpful, treated us like royalty. Roberto listened to what we wanted to look at, he went through the inventory, and we found the one we loved.

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.

The customer service here exceeds the ?Call of duty!? The patients that my sales representative Jermey had is to be compared to a saint. When it seemed extremely unlikely that I would be able to get a feasible finance quote due to high lender suggestions and strange credit inquiry results. In the midst of me throwing in towel my sales representative reassured me that he would not give up on me. He told that he would collaborate with management and the finance person to get me the car. They somehow reduced my down payment six thousand dollars by the next day, and gave me a warranty that covers almost anything. They even went as far as reserving the vehicle for when others came in to buy it. The unfortunately had an unforeseen issue that was not covered by the warranty. I sent a text to Jermey, my sales representative and the manager paid for the repair out of pocket. A lot of people are afraid to buy vehicles from car lots because of shady customer service, and they hate payments. But there is a lot of security at this store. I went to three dealers before this one and one sold the car I wanted while I was actively buying it, and the other two, I wasn?t happy with the car! ?This is where we need to be at!?

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

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!

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.

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!

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

Vincente was very cordial and helpful in finding the perfect car for me! Highly recommend.

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

Our Sales consultant Logan did a fantastic job answering all our questions, being straight forward and was not pushy with us. I will definitely go back and recommend this dealership!

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

Jorge did a great job of finding solutions for my repair and keeping me informed. He did additional research to find exactly what I was looking for.

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.

I was shopping for a vehicle and open to new or used. After looking at several vehicles through the state, I settled on a new one. I had a decent offer from a dealership over an hour away. But AutoNation felt they could do better and save me the drive. And they did just that! The sales team were very supportive and flexible with my needs through the purchasing process. And I am now the very happy owner of a new vehicle!

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?
