Used GMC cars for sale near Castle Pines, CO

Alex Baidutch was my advisor. He was very courteous and helpful. My service only took an hour. I bought my Rav 4 from Auto Nation get all my service done here because I trust theme .

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

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. :)

Thorough, professional, comfortable, and friendly. Bought my Golf here and always come here for servicing.

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.

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!

Easy and fast. Great experience. Thanks to the whole team for a great car buying experience. I will recommend to others looking for a used vehicle.

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.

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

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.

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!

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 just purchased the all-new 2026 4Runner TRD Off-Road from AutoNation Toyota Arapahoe, and the experience was top-tier from start to finish. He made the transition into the new generation seamless and took the time to walk me through the new 14-inch tech interface. If you're looking for the new 4Runner, go see David. He’s professional, transparent, and made sure I got exactly the build I wanted without any of the usual dealership headaches.

Just trade in my 2015 GMC Denali with 140000 miles on it and still holding strong at trade in best SUV I ever had upgraded to the new 2021 Denali and boy do I love this SUV from comfort to outside design just an amazing new well designed SUV.

Quick & Excellent Service! The technician called us with all of the information we needed and provided video of all repairs. They were very friendly and quick turnaround with our maintenance.

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 !

Smoothest and most professional car buying experience I have had over the years. The dealership was transparent as to the pros and cons of the vehicles I was interested in. The sales person made it clear she was not paid on commission and so I knew her input was not motivated to sell me a higher priced vehicle for her self interest. The sales person was a true professional from the very beginning.

Love this place guys were great we love are kia will be back again they help us get what we wanted and not try and do what they wanted

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 initially delighted. The sales staff was awesome and got me into a dream car. Three days after bringing my Redeye home I noticed a small puddle of antifreeze. Two days later the engine light comes on so I had it towed back to the dealership and told them to keep it until they get it right. This is day five. I would still recommend this dealership as long as you buy new. Evidently I bought a Frankenstein. I just hope that this is a one off and am able to enjoy the car for years to come.

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.

Jay quickly found the car I looked at online. He was able to quickly get use in and out of the dealership all in the same night.

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.

One of the best buying experience I’ve had in a long while. Jeffrey was great. Had everything prepared for our appointment. The truck was cleaned up and ready for the test drive. Once we got back we worked on the numbers. They were close, but working with the sales manager we agreed on a very fair deal. And that’s what I appreciated the most let’s be fair with each other. The next day working with Preston in finance was also very pleasant, he worked his magic and got us a great rate with the bank. Overall experience was excellent! I hope I won’t need another truck for while, but if I do I hope the three guys are still working here. Cheers to them. Ask for Jeffery(sales).

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...

I bought a new Subie from these folks and the whole process could not have been easier! Everyone I dealt with was very helpful and efficient. I was able to arrange pretty much everything via phone/email ahead of time, and once at the dealership, very quickly I had finalized the purchase and was headed home in my new car! No surprises, no games or hidden charges, no high pressure sales. Everything was clear and very straight forward. It was definitely worth the long drive for me to go up to Denver for the purchase.

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 had a flat tire and they were able to repair it. I never felt pressure to get new tires, and they fixed it quickly.

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

Their rating did not reflect my experience at all. Adam honored msrp price when ordered w/no addons. Made sure to arrive within 48 hour purchase window.

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.
