Used GMC Sierra 2500 trucks for sale near Thornton, CO under $1,000,000

Great experience at this store when I came by today. Thanks for your help see you next timr

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.

The best dealer I have dealt with. Very nice will get you what your looking for out of vehicle open and honest.

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.

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.

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!

A+ purchase experience with Matt Heintz. Matt is transparent, efficient, and responsive. We drove 60 miles to do business and are glad we did. Best new car buying experience we’ve ever had.

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!

We purchased our Ford F350 about a month ago for a great price with absolutely no pressure or hassles from anybody there. They took our old F150 in trade and delivered the new truck down to Colorado Springs. Mike replaced the cracked windshield before delivery which we hadn't asked for or expected, which was awesome. Already put a hard 5,000 miles on it pulling a very heavy 5th wheel RV trailor in a across country move. The truck performed great and we absolutely love it!

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.

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.

To begin this review, you should know that I rated the facilities a 4-star because, in this time of COVID, I was unable to enter the main building. The lot is cramped with gorgeous, fairly-priced vehicles, plus a small building in the center. There was no room for me to park my own vehicle when visiting, so I parked in the cul-de-sac. Now, about Stan. From the Ukraine, Stan is a compassionate, thoughtful salesman who spent our time together masked (because of COVID) and LISTENING to me as I fumbled with what I was looking for. He asked pertinent questions, took the time to understand what I was seeking, and was as transparent with me about the quality of the vehicle I had come to test-drive as is possible. I pointed out scratches. He admitted that they were problematic. I asked him about the timing belt: had it been changed? He didn't know, and didn't invent a story. He didn't say "yes" or "no," he said the most honest thing a car salesman can say: "I don't know. But I will find out for you." And, sure enough, he did! We talked about the timing belt replacement (which HAD happened, and this saves me $1,000 right off the bat). We talked about the provenance of the vehicle, a wreck it had been in eight years ago, how clean and immaculate the car was, both inside and out. I thought that the car was overpriced a bit, and I asked Stan what he thought. He agreed that it could be a bit lower, and on my first visit to the lot, he informed me that his boss had lowered the price of the car by $500. Which was music to my ears. I test drove the car. It handled beautifully. Ice-cold A/C, no pulling to the left or right. This car had been in a wreck before, but other than the CARFAX report mentioning it, I would never have known. Stan gave me the keys and said "Take this to your mechanic," so I did. I sat at my own personal mechanic's office and waited for an hour while they went through the car, front to back, paying close attention to the mechanical aspects of the vehicle. They found a leaking power steering rack and pump. That's IT. "Lou," said the owner of the shop. "This is the best vehicle you've brought us, and I am of the strong opinion you should BUY THIS CAR IMMEDIATELY." I wasn't sure, given the cost of replacing the power steering rack and pump. I went back to Stan. He wasn't sure, he said, but he'd check with the boss. I offered $500 less than the vehicle was priced at, even AFTER a $500 drop! Stan stood up for me with his boss, got the boss to agree, and sold me the car. In conclusion, I have a fantastic vehicle, low miles for its age, mechanically sound (except for the rack and pump, which I will get fixed on my own dime), and Stan has a customer for life in me. I've been in sales for forty years, and Stan did everything right. He shared what he could do, told me honestly what he couldn't do and, not once, not EVER, did he give me a hard-sell. He listened to me, he met my needs and then exceeded them. Kudos to Stan and to Denver Auto Company for the best car-buying experience I have ever had. Thank you.

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

The salesman was very helpful and went out of the way to help me on this deal. I greatly appreciate his help. I would buy another vehicle from this location and not hesitate to recommend people their way. Again I thank Luis and the people at this location. Keep up the good work!

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.

My experience at Autonation North was highly positive, primarily due to the assistance provided by sales representative Hussian in acquiring a new truck for my enterprise. He demonstrated remarkable patience and exhibited promptness and efficiency throughout the entire process. At no point did he exert pressure to influence my decision; rather, he ensured my complete satisfaction with the selection. I strongly recommend Hussian as an exemplary sales representative.

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 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!

Excellent service and always get my truck serviced quickly and get me out on my way! Very friendly and knowledgeable and give me good information on upcoming service needs.

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

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.

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.

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

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!

excellent bought a good car good prices 100% recommended Fatima nuñez the best group 🙏🏻

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

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

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!

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.

Initially I dealt with Dan, the owner, over the internet. Then I dealt with Steve at Castle Rock, then Martin at Parker. They were kind, caring, and helpful. Honestly, Dan may be the best communicator I've ever dealt with. He always responded immediately, I was mostly impressed with his immediate and accurate responses. I bought a 2017 F350 and I feel I got a great deal and was well taken care of. Thank you Berkenkotter Motors Tomm Olsen Michigan

Elba me atendió muy bien! Encantados con el servicio, muy bien todo el proceso súper rapido

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!
