Used GMC Sierra 2500 Denali for sale near Mountain View, CO

Josh was patient and did a great job. We hope to see him on our next purchase. Asking to use 25 words for this review is annoying.

Foundation Cadillac did it again—and honestly, I’m not surprised! When my 12V battery died on my Cadillac Lyriq, David Hann and his incredible team jumped into action. They did whatever it took to get me back on the road quickly and stress-free. David is truly amazing—always professional, caring, and reliable. If you’re ever in need of service, repairs, or even looking to make a purchase, go to Foundation Cadillac and ask for David. You’ll be in great hands!

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Tons of options in great shape. Whether you're shopping for something newer or more budget-conscious, the lot was well-stocked and well-organized.

I've owned my truck for nine years now it is never once let me down. I'm about to put my first set a tires on it and brakes other than that I don't plan on getting rid of it it's never let me down and after reading all the other reviews it makes me realize they don't make them like they used to as they used too!

I bought a car from Springs Auto Group last month. Shawn and the group at Springs were very professional, polite and not high pressure at all. The process was smooth and easy. I would definitely buy there again.

I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

Working with Scott was a real pleasure. My wife and I were surprised at the attention to detail and his willingness to do whatever he could to make the purchase happen.

Outstanding experience. Christopher, our sales rep was incredible. This is our second Outlander we have purchased from him in under a year.

Leon was great to work with, no pressure and left me with the keys to look and start the vehicle. The lot for cars was well spaced out. Was really interested on what I was looking for. A great place to look for your car.

What a gorgeous truck, runs good, sounds good and has all of the amenities I need although I am looking forward to their next interior upgrade.

Amazing experience .super patient and no hassle team, completely transparent Charles and Rick took good care of us! I would go back there again with my next purchase

Wonderful truck. Has had zero problems. I am trading for a new one. Truck is all original with no modifications. Truck is in excellent condition.

I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

I usually dont write reviews but my experience with Truck Kings deserves one. Erase any idea you may have of a used car dealer and its inventory and replace it with satisfaction, enjoyment, zero frustration and a buying experience like no other. I had found Truck Kings from an ad online for a vehicle and went there to take a look at it. As it turns out they had 3 trucks that I was interested in. All 3 trucks were beautiful, straight and clean. Abe the owner of Truck Kings and I started discussing buying and trade options. Abe displayed a true knowledge of what he had to sell and was forward and honest about the strengths and weaknesses of each vehicle that we were in discussion about. His knowledge and honesty help me in making the decision as to which vehicle I would ultimatly purchase. During our discussion my trade in vehicle was in play and Abe offered me a very fair price on it. Finalizing our transaction I was left with a feeling like I had been treated well on the sell of my old truck and the purchase of my new truck. There were a few minor items on my new truck that needed to be fixed or replaced and Abe said he would take care of them, he did so promptly only a few days after I had taken delivery of my truck. Abe is a man of his word, his word is his bond and he is a gentelman. If you are in the market for a truck, take time to visit Truck Kings-Abe does some amazing customizing work, I get comments on my truck almost everytime I drive it. He keeps clean good looking inventory and I will definitley be back when it is time for another truck. Abe runs a clean, straigtforward and honest shop. He fascilitates a no pressure enviorment and can help arrange several different financing institutions to help you in getting the best deal avaliable.

Quick & Excellent Service! The technician called us with all of the information we needed and provided video of all repairs. They were very friendly and quick turnaround with our maintenance.

Great power and yet great economy. Love the safety features with the cameras and side vehicle warning. Camera that shows side of vehicle, including trailer when turn signal is on is great. Also appreciate the bed camera for hooking up gooseneck trailer.

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

When looking at price point vise equipment, This is your truck. I looked at every 2500/3500 on the market, same vehicle equipment and price. I chose the Duramax.. HP, Torque of this Diesel, truck equipment that the SLT price point had everything that I wanted for safety, appearance and comfort, none other came close. This is your truck...

Helpful and kind, answered all my questions. Next time I'm shopping for a car, I will come to Luis. It's important for me to have someone I feel listens to what I need.

This truck is everything I wanted! GMC, 4x4, Lifted, Low milage. It's going to be great for my hunting and 4 wheeling! I love it!

I had a great experience as a first time buyer from a dealership and my sales representative was extremely polite and very helpful in helping me purchase a vehicle that I liked.

One very awesome vehicle. Checks all the boxes you need in a truck and exceeds expectations on quality, performance, and looks great ,too. Love my nre truck.

I was interested in a new GMC Acadia, specific features and model. Zac Taylor worked very hard to bring a vehicle from the Colorado Springs store. He had everything outfitted as needed, worked out details remotely, then delivered it to me in the mountains. I drove away a great new vehicle at an outstanding price point. Thank you Zac for all of your hard work during this car purchase!

I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

We love the car that we purchased. Our salesperson was easy to work with. We were cash buyers and the finance department handled that well. The only issue is that the car had received a minor repair in the rear fender and during the repair, the dealership failed to reconnect the tail light.

I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

Everyone from the sales rep., sales manager, finance manager and shop team worked to make my experience simple and left a lasting impression. I will absolutely recommend this dealership to anyone in the market for a vehicle.

I have owned my truck for a month and two weeks. Two weeks after owning it my power steering went out for about 25 miles then was OK again. Last week the check engine light went on and after about 25 miles it turned off and it was OK a week ago I entered my truck to start off for the day and everything was dead absolutely had no sign of life. The dealership has now had it for exactly a week and they cannot figure out what’s going on. They say they’re having problems receiving communicating. I sure hope I will continue to love my truck. It drives like a dream and pulls like an ox.

Had a great experience with both Justin and Hunter —- no pressure —- let me borrow car for extended timeframe and lovely people. Would highly recommend visiting their dealership.

I want this truck if I can't get help with finances I'll try againfri and ill have cash. I want it 100percent I've only dreamed of owning a truck like this and now if the Good Lord willing and the creek don't rise.a dream might come true.,!!!!!! I love everything about this ride.just rite for the open road.

Austin was a great help through the whole process and made everything run fluid and smooth. Treated my car like it was his own or a car he was buying. It was almost like he was buying it with me.

Greg Wolaver was a great help in regards to my long distance purchase of a used Jeep Commander. He was up front during the whole process and greatly assisted in the shipping process. I haven’t gotten my vehicle yet but if it’s half as good as he stated it will be a great purchase.

Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!
