Used GMC cars for sale near Boulder, CO

They were a pleasure to deal with and made the process of selling my car easy. They gave me the greatest deal available. I have earned their future business.

2019 Canyon Denali. All sorts of bells and whistles, several that I don't really need. Biggest complaint: no memory seats and no Homelink garage opener. Ridiculous. What accountant made that decision?

Great experience here with Flint, trading on a used vehicle. Service was fast and communication was clear.

Great vehicle for pulling my fifth wheel RV which weighs around 20,000 pounds. This dually truck pulls the RV very nicely without any significant strain on the engine or the transmission. However, like all of today's diesel engines there are 4 different system of emissions on this truck. Each one of these emission systems has sensors associated with them. If one of these sensors goes bad the truck will not perform optimally and sometimes it will go into the limp mode. Unfortunately this is not unique to GMC trucks. All manufacturers are battling this system. Also, I have had to take the truck to the dealer for computer upgrades in order to improve performance. I wish these upgrades could be performed on line (through wifi or with my own phone service). It sure would make things a lot simpler and improve the through put of the dealers who are already strained because of the limited number of available diesel mechanics.

Helped a friend pick out and buy a truck at Red’s Auto & Truck. We worked with Rick Hawkins and he was refreshingly knowledgeable, professional, and polite.

This team worked to find everything that I wanted in a vehicle. They located it on the other side of Denver and delivered it to the lot closest to me on the next business day. The sales and finance team worked with me to get terms that I was comfortable with paying on a monthly basis, as well as an overall price driving off the lot. This is my second purchase of a vehicle with the AutoNation Team at different locations and they always work hard to be helpful and fair.

I love my Acadia Denali. It is fully loaded with anything you can think of.I love the V6 engine and how smooth it drives and rides

Craig T made purchasing a new vehicle from AutoNation Chevrolet North a real pleasure. He was able to coordinate the purchase, final prep, and delivery of the vehicle. I?m extremely happy with my experience purchasing an Equinox EV RS! Craig, Freddy in service, and the General Manager all made the experience extremely positive. I very strongly recommend both the sales and service departments. Ask for Craig. He will set you up with a vehicle that will serve you well!

I saw this car driving by the dealership and automatically was drawn to it because of its color. GMC calls it brown but one print out called it crystal metallic purple. It changes colors depending on the weather. I love the handling, the dash and all the bells and whistles! My grandchildren love how much room that it has!

I had a great experience at south creek! Great inventory, and everyone is so friendly. They got me my favorite coffee while I was waiting, free of charge :)

Got the Duramax Sierra SLT crew cab with pretty much all the options, I’ve tried other trucks and currently have a 2007 Chevy Duramax and it turned me to GM from the ford and dodge diesels I’ve driven/owned in the past. Blows my mind with all the options, super comfortable and rides quite nice for a truck.

Thanks for the Jeep Rick! And thanks for all the help! The Jeep is really neat, I can finally go rock crawling. Dreams really do come true!

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!

Easy to work with, set everything up in a timely manner. Mathew did great explaining all my options. When it went to finance Juan was very knowledgeable and straightforward. Also a bonus is most of the documents are digital now.

Carlos at Super Auto was professional, patient, and easy to work with. He addressed my concerns and showed me several cars without being pushy. I appreciated his approach.

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!

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.

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.

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!

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. :)

Austin was a great help through the whole process and made everything run fluid and smooth. Treated my car like it was his own or a car he was buying. It was almost like he was buying it with me.

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

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)

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

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

Our salesman Eissa Hizhley, was a pleasure working with, he got us exactly what we wanted. Finance Deptment was easy to work with. We will go back again.

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

Good costumer service and very helpful it was what we expected plus they have nice cars

I bought this 2017 Tahoe w LT trim new. Have 60K on it now and have had no issues with it. We are not towing with it or doing high speed racing so we find the 5.3L Motor is smooth and quiet (and have not had any lifter issues which others have reported). Transmission and suspension also smooth. We keep Michelins on all our vehicles and have found this Tahoe very quiet and comfortable for road trips with 4-6 people and luggage. The LT trim pkg deleted some comfort items I wish I had (like heated steering wheel) but it still is pretty much leather-and-loaded so it was a good value at the time. I have had Suburbans for 35yrs before purchasing this Tahoe and I will probably go back to a Suburban for the extra cargo space when I trade this Tahoe in. But this has been a nice and reliable vehicle for us. No complaints.

I just wanted to thank Rob for getting me out of a difficult jamb. My battery was failing, which required multiple jumps, and Rob was able to get me into service immediately even though his schedule was quite full. Rob had the battery replaced within 30 minutes of my arrival. I have never visited Fowler dealership in the past but will make it my go to place for future services.

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

Sergio was very helpful! Good cars at good prices. Would definitely recommend buying a truck here.

I have enjoyed my vehicle. It is comfortable and drives very well. I like the color also. It is very roomy, takes off fast and the safety features are very beneficial.

Jesus Hernandez was amazing and helped with us get into a vehicle same day woo!

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.

Sales and finance teams were extremely flexible and attentive, listening to my concerns and working to find solutions. They supported 2 different test drives when I had a concern about a specific driving condition, being extremely flexible working around my schedule. Cam, Austin, and Alec worked together to provide answers to all of my questions regarding financing and extended warranties. When a last minute issue arose on a Friday afternoon, their maintenance department obtained the part and swapped it out on a Saturday morning to allow me to pickup the car that afternoon. Communication was excellent, receiving 2 status updates that morning.

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.
