Used GMC cars for sale near Thornton, CO under $899,990

We enjoyed working with Andy on the purchase of our used vehicle. He was able to get us exactly what we needed!

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

Anthony Vassell was "entertaining, quick and to the point." He made sure the car we bought didn't get sold while we drove 707 miles one way to purchase it We enjoyed working with him as he answered my questions promptly.

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.

I was in and out what seem like an hour to hour and a half at most and no haggle pricing and with great discounts.

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.

I got a gewat price on my truck, and they were great about replacing the parts that disappeared between when I looked at it and when I bought it. I am very happy with them and my truck!

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 great experience. The mechanic even worked into his lunch to get my repairs done quickly. My service coordinator was excellent and really kept me in the loop with everything.

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!

"Salesman Steven Morris and his team provided excellent service from start to finish. Steven listened carefully to what I wanted and treated me with respect and honesty throughout the entire process. I couldn't be happier with my purchase and the way everything was handled- quick, smooth, and completely hassle-free. I'll definitely recommend Steven and this dealership to my family and friends. It was truly a pleasure doing business with them!" Thank you ever so kindly! ~Keesha N.

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!

Very good experience completed my service in a timely manner and didn’t have to wait long at all

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 !

Great customer service! Becca, my sales rep, was amazing. And Charlie, my finance guy, also did a fantastic job locking me in a deal that exceeded my expectations. I just drove my new Silverado to San Antonio and it handled like a dream! Way better than my old F150?

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?

My name is Jack Walton, I’m had the best experience I am 77 years old and Al Gee filled all our needs. Great service,great staff from sales to finance. I would recommend Also Gee, he was s simply the he best. Great salesman.

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

I enjoyed working with the Auburn Toyota team. They were friendly and helpful. No pressure or games. They helped me get out of my lease and into a used truck. The truck was delivered very clean with a full tank of gas.

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.

Cars appear to be clean, in good repair, and fair prices, appreciate the prompt communication.

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.

Devon Canty was great to work with on an out of state purchase. We got a great car at an amazing 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.

Good people . Very helpful.staff. finance manager was great worked very hard to get me approved.

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.

The service manager was outstanding. He was involved in every aspect of my car repair. My issue was very difficult to diagnose. I observed him interacting positively with employees. I saw him doing manual labor, which you usually do not see. I was greeted positively from the moment I arrived. This is in contrast to the negative experience at AutoNation Chevrolet Pembroke Pines down the street from me. I know a positive business from the moment I walk in. I observe all employees including the amount of time spent with customers or just in the customer area. Happy employees are going to give customers a better experience.

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.

Awesome! Thank you Aaron and William you always exceed my expectations, I know that I am always in good care when you two take my car. Thank you ?

This truck is the definition of mans best friend truly so enjoyable to drive and perfect for the family . My kids and their friends think I’m the coolest dad when I pick them up in this beast

On Saturday of all days, my battery was dead. A friend charged my battery enough that I could get to KYAH and I had called coach who is head of the service department who is fantastic and he said bring it right out. Will get it right in there and get it taken care of and that’s exactly what they did. They get it taken care of. I had no problems. He brought the car out. He explained everything to me about not having to use the key to start the car up, but you can always use the key that’s inside the a little chamber and it just worked really good and he just if I ever have a problem and I come up there he always explains things in detail with me and that’s what you have to do with me. Explain it in detail. It was fantastic. I can’t say enough about The service department at Kia Bev Smith Kia. I cannot say enough good words.

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

Great! Nick Atkinson met me at the entrance and immediately was of help to me. I knew what I was looking for and repointed out the right car. He was good at going through the whole car and showed me what I needed to know. He was very helpful with the whole process.

I own a 2021 Yukon Denali with 23K. At nearly $90k, I purchased every option except for the silly entertainment screens fastened to the back of the front seat headrests. (nice for leaving the imprint of your passenger's faces on the screen in an accident - buy a couple of iPads. First of all, kudos to GM engineers. Technology actually exceeds German cars I've owned. Rear view camera is GREAT and adjustable for brightness, distance and width. But, make sure you purchase the washer for the rear lens...Miirror is almost unusable in rain..(blurring with rain and dirt quickly. I'm 6'2" and really ticked-off there isn't a handle on the "A" pillar to grab to pull into the driver's seat. They put a handle at the upper center of the door opening. What is that for? I have to grab the steering wheel (fortunately rigid with the engine off). Another big problem is the loss of both knees in a frontal accident. With the steering wheel all the way back, I can't even come close to stretching my leg out. Really! A couple of bigger issues: I know the front of this vehicle is right off of the truck, but the end result of the gigantic, unsloped hood, is the inability to see anything 12 feet in front of you. And making right turns.....better memorize that curb before you start your right turn because you won't see it again. Just "that look " from your wife as you run over the curb again with your right rear wheel. Lastly, I hope someone from GM reads this.....With all the awesome high-tech items on this car, why are there no "turn" lights? You know, the lights that let you see where you're going, especially right turns. Porsche has LED lights designated for turns that light up the whole area you're turning into. In the Yukon at least I'll see what I ran over with the terrific rear view mirror! My only intermittent mechanical annoyance is when I push the door handle to lock the doors. It's supposed to fold the mirrors in which is a good way to check you locked the vehicle. occasionally , they don't fold and I have to push the button 4 times. Of course, the mechanic needs only to push the button till it works and tell me it's working. Twice. Guess they win. I'll live with it. Now for the rest: Fantastic overall vehicle! With the air suspension it rides better than Mercedes or Lexus. I always get positive remarks from passengers. The steering wheel control for the Active Cruise control is absolutely perfect. I've driven between Arizona and Colorado without taking my hands off the wheel (just moving my thumb). And the engine, I LOVE THE INLINE 3.0 DIESEL! Almost got the 6 liter but took a chance on the diesel that just came out (in 2021). Same exact torque as the V8 and great for passing. The big difference ..... I had to take a photo of my dash to prove to my friends....heading back to Phoenix with 256 miles on the odometer averaging 30.2 mpg going the speed limit! My Porsche Cayenne gets 19.6mpg (not going the speed limit). The 9 cameras help when parking unless your wife is with you. When I come to a stop I'm waiting for my wife to hold up the 1 to 10 signs like the judges in the olympics. And lastly, For a car that will raise 5" in 4 low, why does the car come with 1 ply polyester sidewalls ? I'm not comfortable on gravel or rocky roads for fear of a sidewall puncture. I highly recommend this vehicle. The designers did a great job making this big vehicle look sleek and smaller than it is. I'm a bit unnerved when I see a vehicle like mine come flying into a parking spot for a perfect 4-point landing and the driver is a 110 lb soccer mom. And I just spent 20 minutes with a micrometer adjusting my position so I don't get "that look" again from my wife. Good luck and hope it's reliable.

Excellent service in a timely manner! Herb is a very good service person and always makes sure that my car issues are taken care of!

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

My mother is thrilled with her new Buick Envista. Comfortable, nice looking, handles well, smooth driving and easy for my 86 year old mother to operate. Salesmen David and Bill were very helpful, as were Scott and Matt. Thank you!

My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Always good service here. They always treat me with courtesy and respect.

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.
