Used GMC Sierra 2500 trucks for sale near Thornton, CO

Buying my first vehicle from this dealership was an excellent decision, an overall outstanding experience.

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!

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 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.

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.

No pressure, really easy to work with. Worked with me on my trade in.

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.

I did my research and found a great deal at Denver Auto on a Subaru Forester. The car was ready and waiting for my scheduled test drive. Right by the door. They let my mechanic look it over. It had just had lots of repairs/maintenance. My mechanic verified all this. Stan was great and I purchased the car!! Still going strong!! Thanks Denver Auto!!!

Love this vehicle. I feel safe transporting my grand daughters. It is reliable. It?s great on highway and city driving. I would recommend a GMC

We had an excellent experience buying a truck here. It started with Ali. He helped negotiate extremely well.. He was very personable and eager to meet our requests. Andre was awesome! He was very professional and was able to give us what we wanted. Taelor in financing was great too! Made the document signing very easy and understandable. Last, we can't forget Brian for getting the rims off our trade-in back to us! Thank you to AutoNation on Arapahoe! It was definitely a painless and very smooth transaction.

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.

Helped a friend pick out and buy a truck at Red’s Auto & Truck. We worked with Rick Hawkins and he was refreshingly knowledgeable, professional, and polite.

So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

The team at Autonation West pulled together and handled a very unique deal I presented to them. Know that when push comes to shove the AW team truly negotiates fairly.

Love my GMC. Owned a Chevy and this absolutely beats it hands down. Never had any issues. Inside is very comfortable and can't imagine driving anything else

I was here at the dealership a few months ago and I traded in my 2010 challenger on a 2014 challenger. The new one I purchased was an absolute gem. It only had about 600 miles on it. I thought “no way will this get approved” I’ll have to drive two hours back home without the new vehicle. Well I am pleased that I had Vincent and Kurt to help every step of the way. Between the two, they got me the best deal possible and I got exactly what I wanted. Never any pressure at all from anyone. The whole team there was exceptional to work with. I couldn’t have asked for a better car buying experience. Thank you to everyone. I definitely recommend going to Omeara. I will for sure be going back when I need to purchase another vehicle. Bill

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.

My wife and I were looking to replace a vehicle; online browsing led us to several choices from Drive N-Motion. My wife visited the location over lunch one day and met Zach. She left with a strong impression and Zach was quick to address our numerous emails. Throughout our search, Zach was personable and knowledgeable. We set the pace for our car-buying experience; Zach always made himself available but never pushed us to move forward. On numerous occasions, he adjusted his schedule to work with my wife and I. As we narrowed our search, Zach continued to provide us with additional options. Once we had sufficiently narrowed our criteria, Zach even searched Drive N-Motion’s incoming inventory and made available additional vehicles which fit our budget. Zach went above and beyond to serve us. He and Drive N-Motion took the car-buying process and made it as pain free as they were able.

This truck would help me thru out my needs I and my family love this beautiful truck, there is no better place for me to shop than the Paso Robles Chevrolet I highly recommend them

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.

Oryn Orozco has been extremely helpful, knowledgeable, professional and very patient. He has been wonderful to work with and has found me the perfect RAV4 XSE hybrid. Can’t wait for it to arrive!

Just the truck I was dreaming. Auto world experience is great on product knowledge high recommend 2500 Hdz Denali truck you won’t regretted price product and drive experience

After any serving of a vehicle taking it through your car wash before returning to customer. This might encourage more customer loyality. Oil change prices are too expensive. The expertise needed to do that job doesn't equalate to charging that amount.

This is the first diesel I have owned. The power is amazing and I really like the room inside the cab. This truck is a beast... Love it!

Rafeal was my contact there and he was great. He went above and beyond to communicate share photos and video and was very transparent. As a matter of fact the whole process and everyone was easy to work with. Not the dealer where sale and sale manager go back and forth to do some crazy negotiating. Open transparent and fair dealing. Rafeal was an advocate throughout and in and out with anew car well less than an hr after trade in paperwork

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!

My experience was great from the time I walked in the door, Luke, Mike, and Kelley were fantastic from showing me what they had in my price range to helping me get approved and out the door with a vehicle. Will recommend them to friends and family 100%

I was in need of a new car . The one i had was bought in 2005 but the year of the car is 2001. I wanted something a bit newer and affordable. I didn't catch the guy's name since my dad was the one who dealt with him first. No pressure at all. He was very helpful. I test drove the car and loved how it drove along with it's a big upgrade to what i had. So decided to buy it. I bought a 2012 Infiniti G25x, leather seats, AWD. front seat heaters, sun roof, backup camera, defrost on the side mirrors and it's a V6. I love it. I highly recommend buying a car here.

I just wanted to thank Rob for getting me out of a difficult jamb. My battery was failing, which required multiple jumps, and Rob was able to get me into service immediately even though his schedule was quite full. Rob had the battery replaced within 30 minutes of my arrival. I have never visited Fowler dealership in the past but will make it my go to place for future services.

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.

Bought my vehicle from Golden, CO Carmax and didn't have any support for mechanical issues. Still purchased the vehicle because it is what I wanted. Ashley from sales in Golden was the worst! I ended up closing the deal with Cora who was amazing and clearly the exception to the rule in Golden. When I told Ashley there were issues with the brakes she was rude and didn't take me seriously. I ended up working with the Federal Heights dealership on repairs. Debbie in the service department took this on and was soooo amazing! She took care of everything and I am so greatful! The technican at this location was amazing as well (I forget his name unfortunately)! It is really a shame that I had to go to another location to get service, but I am so glad that I did. Outstanding job Federal Heights location!

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.

HONEST Abe owns and runs this dealership and is not your stereotypical used car guy. He makes promises and keeps them. He took care of the finer elements of a used truck purchase by making sure everything worked and looked good before we took it home. He also referred me to his audio guy and assured that I received excellent service at an excellent price. I got more than a used truck with Truck Kings, I also got access to their network of trusted professionals to modify and maintain it. I will buy my next truck from Abe again.

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.
