Used GMC cars for sale near Boulder, CO

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!

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!

Good afternoon everyone, yes, I’m a lady and I’m an owner of a 2017 GMC Sierra 1500 Denali, it has a V8 motor fully loaded sunroof & also it has heated seats & steering wheel for the cold winter months & in those hot summer months you have A/C seats nothing better than that am I correct? It’s been times like that wouldnt trade for the world!! So for all you ladies who think BIG TRUCKS are just for men, go out there & buy one have them put on some electronic slide in/out rails & go out & show the shows the boss!! lol 😄 I’m out looking for a new one now either a 2500/3500 pearl white

I had a great experience as a first time buyer from a dealership and my sales representative was extremely polite and very helpful in helping me purchase a vehicle that I liked.

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.

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

The Yukon checked all of my needs, I have plenty of room for my children and my Great Danes. I enjoy driving the Yukon and how it handles, overall love this vehicle!

I can’t thank Brandy enough for helping me with my 4Runner. My wife and I had a very good experience and she did not pressure us into anything.

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!

Seemless transaction from start to finish on my 2025 Ram Promaster. I?m a contractor and needed a new work van. It was ready just in time for the EOY

Great truck, solid engine, comfortable, smooth, and it handles great for such a large vehicle. Get one and enjoy miles of roadtrips with all you can tow or haul.

Ryan, Jarret and Heidi always take excellent care of us each time when we visit for a service, with both of our vehicles. We do Mike Huffman, he was our salesperson

We drove two states over to McKenzie Buick GMC in Milton, FL to meet with Nick and make a purchase on our new Yukon Denali. Customer service was top notch. We were going for their 2019 Yukon Denali to replace a 2008 Tahoe LTZ. We are very pleased with the vehicle. The upgrades are wonderful. Love the cooling seats, the wifi, the HUD and even days after our purchase they have reached out to check on how we were and mailed us a small gift that meant so much. We will definitely use them again if they ever have what we’re looking for on a future purchase. - Brandon Howell 2019 Yukon Denali

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.

Monty was an absolute pleasure to work with! He was professional, welcoming, and incredibly knowledgeable about his inventory. He took the time to answer all of my questions and taught me a great deal about the Jeep Wrangler 4xe. I would highly recommend him to anyone!

Any reviews on this vehicle is not correct. We are first owners and it’s been an excellent truck. We hate to see it go !

We were incredibly happy with Eugene and the service department today! They were fast and did great work!

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. :)

Paul helped me. He was kind, helpful, and not agressive like a car salesman. Angie in finance was great as well. It was a great, fast experience!

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

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.

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.

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!

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.

Purchased new in October 2024. Total miles driven 9,276. Just completed a 4,734.2 mile trip through 9 states. Just a pleasure to drive. My wife and I were on the road 16 days, with only 8 driving days, longest day was 674 miles. Average driving speed was about 72+ miles per hour. Seat comfort was amazing, no discomfort, great considering having 4 back surgeries. Very solid on the road with little or no driving fatigue. Performance was great. Of the total miles, about 500 were in town driving and 300 miles was in 4x4 in a snow storm coming across Northern Texas in April. Average MPG was 26.4 with my best 500mile drive at 33mpg. The diesel engine is very quiet requiring me to check the tach sometimes to be sure I had pressed the off button. Very quiet on the road as well. This is my first diesel and I would highly recommend it. Plenty of power, great fuel economy, quiet and very responsive when you need that quick acceleration. amazingly nimble for a big SUV. The adaptive cruise works great. My previous GMC was a 2009, 6.2L V8 Yukon XL. I drove that one 140K miles over 14 years with nothing but routine maintenance, a great vehicle as well. Very happy with this 2024

Kevin & Marlon were fantastic to work with. Their honesty and integrity is what put things over the top for me. I will be recommending them to anyone that asks.

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

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!

Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

They did a great job of helping me find the perfect pick up. Levi spent a lot of time helping me. A very good experience. After the sale, I had a small issue with the battery and they swapped it out for a new one, no questions asked. Great dealership!

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.

Our first visit. Kevin the service manager was so helpful and Daniel our service writer was on top of all questions we had and our vehicle was done when promised.

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...

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

Bought a new 2025 Sorrento Prestige in March and love it! Second Sorrento but the Prestige is one nice vehicle! And Owen made the buying experience easy and painless! Kudos to Owen and the Peak Kia dealership! Off to Minnesota to see our grandson in my new Sorrento! Looking forward to the road trip!

Okay but what is the best way you can do this for with a good price and a nice price for a decent price like this one for like two or five years and a good price for a really good quality one of the ones that I got from the
