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 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.

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

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.

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.

Juan casillas me ayudo comprando una troca en el 2022 y fue muy buen servicio de su parte, hasta la fecha cada que le marco por información me ha ayudado....

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

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!!

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. :)

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

I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

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

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)

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.

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!!

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! 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!

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

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

Nice visit. Needed carpet on back seat removed in order to search for source of rattling noise. Not sure it?s fixed yet, but can see evidence that they tried..the carpet piece wasn?t put back exactly same as original.

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!

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.

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!

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.

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.

I?m not sure how I didn?t notice the air compressor during the test drive but regardless, I bought the car and I do love it so far! To be fair Alex did mention a noise from the AC but again I didn?t hear it during the test drive.

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

Bought 2 cars. An Audi Q5 2 years ago and a BMW X3 m40i this year. Outstanding service on both vehicles. Owen was my sales guy on the BMW. He was knowledgeable, friendly and very helpful. I left some keys in my trade in. He recovered and mailed them to me. I recommend Peak Kia, Littleton.

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

Ryan is the best! The entire Jeep team is always so knowledgeable and helpful.I recommend Jeep and Jeep Services to everyone. So grateful for them. And I love my Jeep!

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...

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

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 !

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.
