Used GMC cars for sale near Boulder, CO

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.

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. :)

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

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.

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

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

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

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.

I have bought two promasters from these guys in a bout six months time. As a business owner I don't have much free time was able to get in touch with Jeff Hale and put the ball in his court. It was the easiest purchase iv made I spent maybe 1 hour each buy at the dealership just to shake hands sign pick up and out the door ! No hassle got what I wanted for the price I wanted even a little cheeper. Will keep my business here!

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.

No one likes the process of buying a car, but AutoNation Southwest actually made it a pleasant experience for me! Sadie and then Lauren were both awesome to work with, professional, knowledgable about the vehicle (Jeep Wrangler Rubicon) that I was looking for, and they were both able to help me, without any bickering and in-fighting like I have seen at other dealerships. Financing was pretty quick, and the dealership was very accommodating about letting me swap Jeep mods out with the new one I purchased. Like they let me switch my after market 37' wheels, so I could have my wheels on my new Jeep. The entire process was as enjoyable as it can be, I felt heard, taken care of and respected. I will 100% buy a car from AutoNation Southwest again. Even if you have had a bad experience at one of the other AutoNation dealerships (I am talking about you, AutoNation West) give ANSW a try, you will not be disappointed. But ask for Sadie or Lauren...they are rockstars!!

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

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.

I own a 2021 Yukon Denali with 23K. At nearly $90k, I purchased every option except for the silly entertainment screens fastened to the back of the front seat headrests. (nice for leaving the imprint of your passenger's faces on the screen in an accident - buy a couple of iPads. First of all, kudos to GM engineers. Technology actually exceeds German cars I've owned. Rear view camera is GREAT and adjustable for brightness, distance and width. But, make sure you purchase the washer for the rear lens...Miirror is almost unusable in rain..(blurring with rain and dirt quickly. I'm 6'2" and really ticked-off there isn't a handle on the "A" pillar to grab to pull into the driver's seat. They put a handle at the upper center of the door opening. What is that for? I have to grab the steering wheel (fortunately rigid with the engine off). Another big problem is the loss of both knees in a frontal accident. With the steering wheel all the way back, I can't even come close to stretching my leg out. Really! A couple of bigger issues: I know the front of this vehicle is right off of the truck, but the end result of the gigantic, unsloped hood, is the inability to see anything 12 feet in front of you. And making right turns.....better memorize that curb before you start your right turn because you won't see it again. Just "that look " from your wife as you run over the curb again with your right rear wheel. Lastly, I hope someone from GM reads this.....With all the awesome high-tech items on this car, why are there no "turn" lights? You know, the lights that let you see where you're going, especially right turns. Porsche has LED lights designated for turns that light up the whole area you're turning into. In the Yukon at least I'll see what I ran over with the terrific rear view mirror! My only intermittent mechanical annoyance is when I push the door handle to lock the doors. It's supposed to fold the mirrors in which is a good way to check you locked the vehicle. occasionally , they don't fold and I have to push the button 4 times. Of course, the mechanic needs only to push the button till it works and tell me it's working. Twice. Guess they win. I'll live with it. Now for the rest: Fantastic overall vehicle! With the air suspension it rides better than Mercedes or Lexus. I always get positive remarks from passengers. The steering wheel control for the Active Cruise control is absolutely perfect. I've driven between Arizona and Colorado without taking my hands off the wheel (just moving my thumb). And the engine, I LOVE THE INLINE 3.0 DIESEL! Almost got the 6 liter but took a chance on the diesel that just came out (in 2021). Same exact torque as the V8 and great for passing. The big difference ..... I had to take a photo of my dash to prove to my friends....heading back to Phoenix with 256 miles on the odometer averaging 30.2 mpg going the speed limit! My Porsche Cayenne gets 19.6mpg (not going the speed limit). The 9 cameras help when parking unless your wife is with you. When I come to a stop I'm waiting for my wife to hold up the 1 to 10 signs like the judges in the olympics. And lastly, For a car that will raise 5" in 4 low, why does the car come with 1 ply polyester sidewalls ? I'm not comfortable on gravel or rocky roads for fear of a sidewall puncture. I highly recommend this vehicle. The designers did a great job making this big vehicle look sleek and smaller than it is. I'm a bit unnerved when I see a vehicle like mine come flying into a parking spot for a perfect 4-point landing and the driver is a 110 lb soccer mom. And I just spent 20 minutes with a micrometer adjusting my position so I don't get "that look" again from my wife. Good luck and hope it's reliable.

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

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.

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

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.

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.

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.

We love our new Yukon thanks for all your help!! Very fast, and helpful staff, appreciate everything!!! Carolina was very nice and very helpful and made our buying experience amazing!!

Katie in sales was awesome to work with! She went out of her way to ensure we had a smooth purchase from start to finish.

We just purchased a car at Mountain States Toyota and are extremely impressed with transparent, straightforward experience. They have an extensive inventory and the salesperson, Hunter, is an asset to the dealership. Hunter's customer service was the main reason we bought a car here. His knowledge is amazing and either he answered our questions or researched them and followed up. Just a great experience!

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 !

It was fast and efficient. I've purchased and service all my Hondas since 1992 from this dealership. This rating process takes a bit too much time though.

I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

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!

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

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!

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.

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.

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

Easy and friendly to deal with. Everyone wants to get a deal done and will work with you.

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!

Excellent customer service from beginning to end. I would highly recommend. There really isn?t much else to say other than I would recommend. Please tell others

I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.
