Used GMC Sierra 2500 trucks for sale near Denver, CO

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.

James at in the service department went out of his way when an appointment I had was accidentally cancelled online. He noticed, checked in, and got my service rescheduled immediately. He provided multiple tire options and a competitive price. The tire process is much faster here than others Ive used and they offered a dropoff if I wanted to go home.

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.

All I can say is that my mechanic is a phenomenal absolute mechanic that is humble for his years and an awesome all around person, I absolutely cannot say enough good things about Autonation Ram and your maintenance and repair team. Huge love and very thankful for such an outstanding group of folks.

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.

I had the recent pleasure of working with Kayla on the purchase of my 2nd truck from Prestige, and she was amazing. Made the buying experience great, which is not usually the case at a dealership. I would recommend going in and working with her to anyone looking for a new car. Thoughtful, honest, nice! Thank you Kayla!

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.

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.

Had a great experience buying my Jeep. Would definitely come back to purchase from them again.

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.

I came to interstate Ford to have a recall issue taken care of. Mary Jo Fuletti helped me with that problem. I told her that there were other concerns regarding my F150 truck. She listened to my concerns and translated them so that her mechanical staff would understand what needed to be looked at. After an inspection, I was informed that there was about $5000 worth of work to be done. I have a Toyota warranty for the vehicle having bought it used from a Toyota dealer. Mary Jo had difficulty getting a response from the warranty folks but she was tenacious and got an inspector from the warranty office to come look at the truck and approve the work that needed to be done. Through Mary Joe’s and interstate Fords efforts, I had a total of about $6000 worth of work done with no out-of-pocket charges. I will definitely be back when my truck needs service or work. They have earned my respect and trust. I’m

Great service it was quick and easy purchase I love my new car thank you

in and out in 3 hours fastest time ever buying a car no complaints. had excellent help in Eric buying the car it was exactly what we wanted

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.

Timely, courteous and professional experience. Service fix explained to me in detail along with charges of repair. Comfortable waiting area. Technician was friendly and courteous.

Best experience I’ve ever had, Nelson was awesome, super knowledgeable and a very honest kind person got to meet Paul the Gm and he was also extremely helpful and nice. Thank you

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...

I was very pleased. Very straight forward. Upfront. Didn’t seem to have any issues at all. I’d purchase from again without hesitation

We were extremely happy with Transwest GMC and will defiantly be buying from them in the future. They got us in and out very quickly and professionally.

This team worked to find everything that I wanted in a vehicle. They located it on the other side of Denver and delivered it to the lot closest to me on the next business day. The sales and finance team worked with me to get terms that I was comfortable with paying on a monthly basis, as well as an overall price driving off the lot. This is my second purchase of a vehicle with the AutoNation Team at different locations and they always work hard to be helpful and fair.

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!

Megi has helped us into three vehicles over the past year, and every experience has been efficient, seamless, and genuinely enjoyable. She’s not only incredibly knowledgeable and responsive but also an absolute pleasure to work with. Megi goes above and beyond to make the process smooth from start to finish. We highly recommend her as both a person and a trusted partner when you’re looking for your next vehicle!

This was my second time purchasing a car from the dealership and had another great experience. Dan and Frankie were very helpful in picking out a car and were very honest which was important to me. I highly recommend shopping here for a great used vehicle.

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.

We had a great experience with this dealership! I highly recommend using Jeremy Tabangay as your salesman. He was very polite, and wasn't aggressive in his sales tactics. He really made you feel like you weren't just a number to him. He also did a follow up after we purchased, just to make sure that everything was going well. I would also like to give Matt (finance department) a good review. He was fun to work with on the financing of our vehicle, and didn't pressure us into buying any add ons. He was also very quick in getting all the paper work filled out. We really enjoyed our entire visit there. I would use this dealership again in the future. Especially, if I was working with both of them.

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.

Ace was fantastic. Kept me well updated and educated throughout the process, and was very responsive when I had questions. The tech was also fantastic, making sure my alignment was dialed on just right

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.

Always a pleasure to get my truck serviced at Mike maroone Chevrolet, gmc, Longmont. Joe was my service advisor and got my truck in and serviced a lot faster then i expected. Service was an awesome. Thank yous

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!

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

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!
