Used GMC cars for sale near Boulder, CO

Very nice and friendly staff. Excellent service. Explain and answer customers FAQ . They have different models and deals for every customer what ever your style or your budget.

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. :)

We had the absolute joy of working with T while we bought our vehicle. T went above and beyond in so many ways - by coming in on her day off to help us out, adjusting her schedule to accomodate ours, being open and honest about the vehicle we purchased and the dealership itself - she was able to answer all the questions we had. We even had a small issue (no one could have known at the time of purchase) pop up a week or so after we purchased the vehicle and T was able to get it fixed for us, no problem. And - you know how buying a car usually takes all day? Not here. It took less time than any other place we have bought a vehicle, which is amazing. Thank you, T! You are the best!

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.

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

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.

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.

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.

Helpful and kind, answered all my questions. Next time I'm shopping for a car, I will come to Luis. It's important for me to have someone I feel listens to what I need.

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 in need of a new car . The one i had was bought in 2005 but the year of the car is 2001. I wanted something a bit newer and affordable. I didn't catch the guy's name since my dad was the one who dealt with him first. No pressure at all. He was very helpful. I test drove the car and loved how it drove along with it's a big upgrade to what i had. So decided to buy it. I bought a 2012 Infiniti G25x, leather seats, AWD. front seat heaters, sun roof, backup camera, defrost on the side mirrors and it's a V6. I love it. I highly recommend buying a car here.

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 !

I feel like I can drop in and shoot it any time with dealership. Saved me on a bunk warranty as well! Always feels like Family!

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

Auto Nationwide is the best. My name is Teresa and I purchased a 3500 ram. Tina was so helpful. She was amazing and the manager that did our paperwork. I’m sorry I forgot his name but he was awesome. He knew his stuff he knows all about the Rams. I was very impressed and very excited about my new ram if you’re looking for any rams or trucks I recommend AutoNation GMC in Golden Colorado, the best dealership I ever experience

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.

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.

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.

No pressure sent car up from Springs location to make it easier on us, Let us look it over, drive it, never any pressure. Andy and Shana are great Also a great family owned business, no haggling, no hidden costs you need to stop in and check for you next car here!!!

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

Great service and love my car! Very professional and helpful in selection and all the paper work!

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!

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

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!

Everyone at this dealership is a class act! Great service. Ask for Ed Rivas to be your lead salesman. He will treat you right and take care of your needs. Extremely knowledgeable and responsive!

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 had to have a front suspension harness replaced due to a squirrel. AutoNation was able perform the diagnostics quickly and got a harness on order.

We recently purchased a 2023 F-350 from Erin in Loveland. We live in Evergreen [approx 75 miles away], Erin had our deal and all docs ready for us to sign. Felt very comfortable with ClearShift and would definitely recommend to friends and family! Worth the drive for sure!

Very knowledgeable, and the personnel explained everything in great detail. The problem was corrected very quickly, and I was confidant driving away with the results.

Elba me atendió muy bien! Encantados con el servicio, muy bien todo el proceso súper rapido

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.

Our salesman Tim was great, he really knew his stuff. He was very knowledgeable. We didn't feel pressure to buy a vehicle. Smooth sale , great salesman

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.

Professional from the start and they were not as much pressure as so many other dealers.

Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

They provided Quick and friendly service and was ready for my car when I pulled up. The staff remembered me from my last service visit. The facilities are always clean.

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.
