Used GMC cars for sale near Boulder, CO

Emmanuel helped me get into a new car, was extremely professional and the process was not as long as I was anticipating. The dealership was open to negotiation and met my bottom line.

I love it so much lots of space .. every thing clean no dents or scratches every thing is perfect all everything fully loaded the best

Great buying experience except for the finance process, which took way too long. The vehicle itself was recently serviced and new Michelin LTX M/S

Nice styling,interior has a new design dash which is beautiful and convenient,safety features and cameras are great and easy to used and the active cruise is awesome.

I have been having my cars serviced by Auto Nation after buying them from Auto Nation. I have been so happy with the trusted service I receive here that I have purchased 3 Jeeps from them over the last 24 years.

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!

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

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

I purchased my vehicle through Sill-Terhar Lincoln - Broomfield CO and had an amazing experience working with Anthony and Kelly. This was my first time purchasing a vehicle out of state which was very nerve wracking. Anthony was my eyes and ears throughout the entire process. He was sending me videos of the vehicle and keeping me up to date on the big things. Kelly was absolutely wonderful. With a two-hour time difference, he was still answering my calls and/or text immediately every step of the way! They are a phenomenal team and were a pleasure to do business with. The paperwork and transportation were seamless, and they held my hand throughout the entire process. Huge Thank you to them!

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

Execlente servicio por parte de Andréa ,joe y Erick buen trato amabilidad y calidad de servicio. I highly recommend Fowler because they are so patient, and help me understand every question

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. :)

DJ was my salesman and he did an amazing job! I highly recommend going to Alpine Buick. The Facility is beautifully represented. Always eager to help.

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.

Got me in a great new jetta at a great price the sales person was really good at her job and I'm very satisfied with my new car!

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.

Zach at Corein did an excellent job helping me purchase my Tundra. Corwin did a great job building extras that were value add to the Tundras. No pressure and they worked with me on numbers.

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 had a great experience purchasing my used car thanks to Juan. He was professional, honest, and very helpful throughout the process. Everything went smoothly, and I really appreciated his transparency. Highly recommend working with him!

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!

Exceptional. Much better than expected. Competent sales staff, and finance. Very fast, no issues. I recommend this Autonation. When another car is needed, I will absolutely look here

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

Kyle was awesome and worked around all our crazy day circumstances. We will definitely be back in the future.

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

Amazing! Always such great service. The staff is wonderful, so friendly and kind. I went for an oil change and they were so quick and efficient.

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!

Julia was so wonderful to assist me on my first car purchase. We didn't take long.

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 like the service I receive from the service department every time I bring my vehicle in for service.

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.

Tonya, Nathan and others have been terrific through the process towards purchasing my new Ford Escape Hybrid. Thank you. Tonya has truly been one of the absolute best vehicle sales representatives that I have ever had helping/taking me through a new vehicle purchase. A big thank you, to you Tonya, for all you continue to do. Working with you is absolutely the best! Thank you!

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

We arrived less than 60 mins before closing on a holiday. We were super impressed and we went home with a new car. It was after closing and more than one person was still there working. You don?t see that these days. Our car salesman even took a selfie with us.

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

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

This Yukon has all the bells and whistles. It is a joy to drive, the drivers area is like a cockpit with everything at your fingertips.

Mick Hasley and the team are patient and friendly. When they say they will call back they do, and they are not in a rush, they listen to what you need. I had a 100+ questions as i had not purchased a new car in many years. I was searching for just the right car for my wife, and they listened to what I wanted, and not what they had in stock. Their online chat service is pretty good too if I have a question I think of, I ask the chat and it gets to the rep and they replied. Honest about prices as well.

This car is a fabulous car for family and traveling. It is roomy, has capacity for kids and sports gear, and is safe. I have been rear ended twice in a Yukon and there was minimal damage to the Yukon and extensive damage to the other vehicles.

Good service, nice cars Juan Lagarda was incredible! He took care of me and his commitment was perfect He is awesome; the best!

Strong body and smooth and safe ride, but still has such a comfortable soft feel . Wonderful for road trips and towing. Sleek design. Excited to take on trips around US.
