Used GMC cars for sale near Brighton, CO

Amber did an amazing job getting my vehicle in for service. Brake job was completed perfectly, exceptional loaner vehicle and the hand car wash is always a nice touch.

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.

Jim Albright Is hands down one of the best sales agents I have ever had the chance to work with. No pressure just leads and understanding of my wants and wishes. Was best car buying experience I?ve had to date

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.

It was a very good experience. The personnel there are friendly and helpful and create a very comfortable atmosphere that would be highly appreciative of anyone interested in buying a car. They give options without being too suggestive and respect the customers decision. If I could give some advise, I would always provide 2 sets of keys to the customer. I only got one and I feel like I should not have to deal with going somewhere else to buy a spare in case of something happening to the original key. The customers down payment should allow for 2 keys.

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

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

handles and drives great, the electronics don't always work, mirrors don't always work, spray with wd 40, check engine light, EVAP culprit, auto nation has no luck with this, will drive it till the warrenty expires and its back to ford for me

I bought my car here and had great experience. I appreciate their kindness They changed oil and it was great checked car out too for free. When done they explained everything.

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 !

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

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. :)

Sophia did a great job explaining everything and helping us with a fast process as well as she found the best deal

2024 GMC sierra 1500 duramax 3.0 is great truck. Great ride and great MPG. 100% recommend to any prospective buyer. Love the truck and how it perform.

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.

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!

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.

Jetta #3 for me, was able to step it up to the SEL package Brandons help

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!

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!

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 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.

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

​I recently purchased a vehicle from the Centennial location and had an excellent experience. The sales staff were fantastic and created a genuine, no pressure environment, which I greatly appreciated. I am absolutely loving my new car and would highly recommend this dealership to anyone.

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!

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!

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

Excellent and reliable, only thing buyers have to do is buy a AFM disabler that you can stick into OBD2 port to avoid lifter failure (longer story, nobody wants a V8 to run in V4)

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!

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.

5 Stars all around for these guys! Thanks for the fast, quality service and friendly employees: I?ve purchased and serviced my car here and have had no issues.

If you like big vehicles and have a family, it's the perfect car. Lot's of road trips watching movies in the back. The Denali package makes it stylish and comfortable.

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 purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

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.

Worked with Sergio and sales team, they did an excellent job through the whole process and made the experience go smoothly. This is my second vehicle purchased from the Auto Nation team and both times the experience has been positive.

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.
