Used GMC Sierra 1500 trucks for sale near Dacono, CO

Echo Park had the best combination of price and inventory of our desired vehicle. Sales associate Delia was very helpful and courteous throughout the process.

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

Julia Vargas was very helpful and kind as well! She also seemed very knowledgeable and we appreciate her service very much!

I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

I had the best car buying experience ever! Jacob was amazing from the time I called and spoke to him on the phone and met him in person. He found the perfect car for me! The finance department got the loan done quickly and was very straightforward and kind. In conclusion, Everyone was friendly, had my best interest in mind, and was very professional. I literally was in and out. Easy peezy!

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

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!

I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

Very good sales experience with sales rep Jim Gallegos at Mountain States Toyota. He reserved a Corolla for me and kept me informed by phone as to when the new Corollas were arriving. I got a decent discount off MSRP. He also pointed out the features of the new Corolla engine design, was helpful on the test drives, and explained the digital display operation. Mountain States Toyota was the only dealer I visited in the north Denver/Boulder/Longmont Colorado area that does not charge the high "documentation fee," so you are able to simply negoatiate a fair percentage discount off the Toyota MSRP on the window sticker (which includes the mandatory Toyota destination charge). I also appreciated the fact that the only add-on charge was for a set of good quality Toyota floor mats and trunk liner that came directly from Toyota already in the car. They offered other items for the car and a Toyota extended warranty, but there was no pressure to get them (and I declined, though I can get the warranty later). Some other Toyota dealerships order the cars with more expensive add-on items installed, that you may not want. I also got a welcome text from the general manager after my first visit asking if needed any assistance with selecting a car. So overall a very good experience with sales rep Jim Gallegos and Mountain States Toyota.

I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

I took my car in for service, and service advisor Erin Schwarz met me. She was not only helpful, but provided caring, attentive service which I truly appreciate!

My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Foundation has come a long way since a couple years ago. They follow up with phone calls about the status of my truck. And explain what repairs need to be done and why. They are not pushy but are courteous.

I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Very friendly and knowledgeable staff. Great customer service. Everyone made us feel right at home. I had been watching the website and finally found what I was looking for.

Great performance, hard to clean, everything, I expected. Getting lots of compliments and head turning. Stomping with thee BIG DAWGS!!!! Good gas mileage on highway.

Was looking to trade in my 2019 Raptor and found an Explorer Tremor. The deal was easy, fast and the salesman was very accommodating and knowledgeable.

Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

Excellent customer service from beginning to end. I would highly recommend. There really isn?t much else to say other than I would recommend. Please tell others

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

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!

This truck has a jerk when changing gears sometimes. I enjoy the truck overall easy to handle and comfortable. Drive with ease sight is good when driving.

I been buying cars for over 15 years and this is the best place I ever been thank you so much to jay the manager and Ryan . Jay the manager give me a very good treat even on my work clothes very respectful person.

Easy purchase experience, would recommend to anyone looking for a new car. Everyone there was friendly and made the whole process as smooth as possible

Very good experience made the process easy left with a new car all the workers are great!

2021 GMC sierra 1500, 5.3, crew cab 4x4, 21000 miles. brakepad monitor lites up. dealership says needs brakes and rotors in back. one mo. on warranty. our rural roads dirty up the monitor. Needs new monitor. brakes look great to me. No noises. dealer says parts on order GM strike. Can't replace myself cause of computer...

Lewis was good I love our cars thank you much for the service I appreciate it

My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

I have purchased a number of vehicles from this location under different ownership. The one good constant has been the service department and the service tech Dave Singh. Ask for Dave he will not let you down.

I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

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

I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

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 bought my first car here! And Jonathan helped me with choosing what one is right for me! He was very honest and was very patient!

This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

Great experience! When I contacted Weld County Garage about a used vehicle, Sales Consultant Miguel Orozco provided exceptional service. Due to my 1.5-hour commute from the WCG location, Miguel provided photos and videos of the vehicle so I could be sure it was worth taking a full day off. I later learned that Miguel had come in on his day off to assist me, a gesture I genuinely appreciate. Having visited numerous dealers in my search, Weld County Garage stood out as the most helpful, professional, and customer-centric. They were not just interested in making a quick sale, but in understanding what I was looking for and finding the right vehicle that fit my needs and those of my family. Unlike many dealerships, WCG encouraged me to take the vehicle to my mechanic for a pre-sale diagnostic check, and all details listed on/about the vehicle were 100% correct. Like many, I have never had a pleasant experience purchasing a used car. However, thanks to Miguel and Craig, the entire process was painless and drama-free, instilling in me a newfound confidence in car buying -- especially with the right dealership staff. Thanks for a great experience, WCG!

Looked at more expensive truck with less options, bought the GMC SIERRA AT4 Turbo Diesel 6. I now only put fuel im once a month. And long distance trips are easier due to better fuel economy. One of my best investments ever.

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 needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.
