Used GMC Sierra 2500 trucks for sale near Thornton, CO

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'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.

The experience of buying this Dodge ram truck from this dealership was exceptional! The dealership was courteous, professional, attentive, and kind. It was a really great experience!

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

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 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.

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!

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

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!

Was in another dealership and saw the same jeep on line at SW - while waiting for offers - I messaged and set up buying process in a quarter of the time I was sitting at the other dealership. Walked in, looked at jeep, sat down, got final offers and was out the door in an hour - only wait time was waiting for detailing to be done by tech which I was grateful for! Simple, easy and efficient!! Love it and highly recommend taking a look here if your in need of a new vehicle!!

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!

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.

Chris at Interstate Ford was absolutely amazing. He searched his inventory for a vehicle that I could afford. I would shop there again!

We had a fantastic experience at AutoNation Subaru Arapahoe. We were just starting our car search when we decided to stop at Subaru out of curiosity. Even though we had never owned a Subaru before, Bryan helped us figure out that the Forester was the perfect choice for us. We drove away with our 2025 Forester that day and haven't regretted it! We experienced excellent service by Bryan and Zachary (LoveSubaru).

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!

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!

Professional from the start and they were not as much pressure as so many other dealers.

We worked with Leon and Aaron(finance), got what we wanted. They were great! Highly recommend. Thank you!

I live in the Indianapolis area and found the SUV my family was needing. I talked to Shawn and told him I wanted an honest description of the vehicle before I drove 5 hours to purchase it. When we got their it was exactly what he described. I would definitely buy from Shawn again!

I had a great experience buying my truck sight unseen with the help of my salesman Tony he went above and beyond with pictures and videos that I requested that made me comfortable with my purchase it was everything he told me it was and more. He rode the sale all the way to the end and took care of every detail I would definitely recommend him to anyone who was looking at buying a vehicle from him especially if you were not able to be there 👍👍

this truck fits my needs better than the other 2500 models. Its hauling and towing performance along with its many people comforts will satisfy us for a long time to come.

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 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.

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

Carlos at Super Auto was professional, patient, and easy to work with. He addressed my concerns and showed me several cars without being pushy. I appreciated his approach.

Yamile was knowledgeable, professional, empathetic and a terrific asset for you. She is a keeper!!! I could not be more pleased with the service she provided.

Some of these reviews are stupid...they offer a no haggle price...period. They were amazing, great service, great price, the only place I would buy a car at

I had an excellent experience working with Dominic Bosco at HM Brown. He was communicative, informative, and never pressured me to move faster than I was comfortable with. Before coming to HM Brown, I had spent time at a couple of dealerships test driving cars, and the difference between working with Dominic and the typical dealership sales experience was night and day. Dominic made the process smooth, transparent, and stress-free. Even after purchasing my car, Dominic followed up to make sure everything was going well, which I truly appreciate. I’ve had my car for a few weeks now and couldn’t be happier. I would highly recommend HM Brown and Dominic to anyone looking for their next vehicle!

Sales and finance teams were extremely flexible and attentive, listening to my concerns and working to find solutions. They supported 2 different test drives when I had a concern about a specific driving condition, being extremely flexible working around my schedule. Cam, Austin, and Alec worked together to provide answers to all of my questions regarding financing and extended warranties. When a last minute issue arose on a Friday afternoon, their maintenance department obtained the part and swapped it out on a Saturday morning to allow me to pickup the car that afternoon. Communication was excellent, receiving 2 status updates that morning.

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.
