Used GMC Sierra 1500 Denali for sale near Highlands Ranch, CO

We brought my car in for an oil change. During my previous visit it was determined that I needed to change my air filters. The week before we brought in my car for service my husband changed 2 filters. At our current visit I was told they needed to be changed (again). In the future please have your mechanic look under the hood to make sure they have or have not been changed (not just go on the notes in the computer).

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.

Sam was incredible! The whole process was smooth and quick. 10 out of 10. No notes.

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?

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.

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

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

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.

Nicholas Nichols was a great salesman and helped me find the perfect car. Ryan Griep was a terrific finance guy and made the financing process super easy.

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.

Thank you, Leon! I had an outstanding experience at Rocky Mountain Eurosport while searching for a Lexus vehicle. Leon, the sales representative was exceptional in understanding my needs and guiding me through the process. The purchase went smoothly, and even though it was an as-is sale, the dealership went above and beyond to assist me with minor user error issues. Their professionalism and timely responses to my calls truly impressed me. I highly recommend Rocky Mountain Eurosport for anyone in need of a vehicle—you won’t be disappointed!"

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.

Bentley Denver knows how to work with you to make sure you are completely satisfied. They sell the best products and match them with the best customer care whether you are a local customer, or like me, an online buyer.

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 I have to do this again good staff George sourial was great handling my purchase. Would recommend every one to going and get a quality vehicle.

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

Very nice and friendly staff. Excellent service. Explain and answer customers FAQ . They have different models and deals for every customer what ever your style or your budget.

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!

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.

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.

Love the color Joose! All members of the team were great and easy to work with. Sales process was simple and not dreadful as every other outside experience was. Would highly recommend!

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.

Went above and beyond all expectations! The team is very responsive and helpful, all of our questions were answered in a very professional manner. I would definitely recommend this place to anyone who asks.

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.

Love this place and definitely recommend Alan Roque, the best worker there is definitely 5 starts.

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 inquired about a Camaro Convertible that had just arrived, Pablo replied and actually sug the car our if the snow and did a complete video walk around. Since I live 400 miles.away and this was exactly the car my wife wanted I was excited to have Pablo helping me. I asked him to look into the price and I had one more to call on. I called back the next morning got the price, made an offer. Unfortunately we where to far apart and the other car sold. My bad luck.

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.

Great experience. Good people. Very friendly atmosphere . Thanks to pre-owned vehicle manager G. W.

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

Lewis was good I love our cars thank you much for the service I appreciate 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!

Easiest car deal I have ever done. I have and will recommend them to anyone. I will be back the next time I buy another truck. Thank you guys. It was worth the 2 hour drive.

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.

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

Matt our salesman was awesome and listened to exactly what we needed along with Tony in finance we walked out with what we needed at the monthly price we asked to be at.

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.
