Used GMC Sierra 1500 AT4 for sale near Lone Tree, CO

Danny gave the best customer service experience. He was very accommodating and worked with my schedule. He made me feel like I was no trouble at all. The nicest person ever. I will ask for him if I ever need service on my car.

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.

7 cars now! They rock!!!! Loving the new truck and jeep! 2025 Ram 1500 longhorn and 2023 jeep grand cherokee l summit! Years of purchasing here, they know financing!

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

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

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. :)

My experience with Castlerock Chevrolet since 2020 one of the best. I appreciate their customer satisfaction. Puts their customers first. My car engine almost destroyed by an oil change of a place I used to get by cheaper but no more. Thank u again.

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...

Great I have to do this again good staff George sourial was great handling my purchase. Would recommend every one to going and get a quality vehicle.

My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Initially I dealt with Dan, the owner, over the internet. Then I dealt with Steve at Castle Rock, then Martin at Parker. They were kind, caring, and helpful. Honestly, Dan may be the best communicator I've ever dealt with. He always responded immediately, I was mostly impressed with his immediate and accurate responses. I bought a 2017 F350 and I feel I got a great deal and was well taken care of. Thank you Berkenkotter Motors Tomm Olsen Michigan

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 !

This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

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!

Was one of the best experiences we have ever had with purchasing a automobile. I would buy from them again. Thanks for being honest people.

This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

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.

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!

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.

Sold my car to Autonation. It was an extra, so we weren't replacing it. Of course, a dealer paid wasn't great. But Chris Corringan was great to work with. He did exactly what he said he would do, WITHOUT any bait-and-switch tactics. When we're in the market for another car, we'll definitely give them a first try.

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!

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!

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 2025 Subaru Forester Sport and received excellent service from the sales and finance associates. The only downfall was that we were quoted a price for the Starlink ( My Subaru) app that was much lower than the actual price.

Purchasing a vehicle can be very stressful, we did not get that while discussing the potential purchase of a new vehicle. Jovanni was very patient with all of our questions.

Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

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.

Some of these reviews are stupid...they offer a no haggle price...period. They were amazing, great service, great price, the only place I would buy a car at

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

Annissa Medina has helped me so much taken care of everything for me and is always so sweet, understanding, and very helpful with everything that I’ve needed. Her communication skills and personality along with professionalism always reassure me that I am going to get the best service and make me feel like I am always welcomed.

Pleasant and friendly We were treated with respect and kindness Would buy another car from this dealership and sales Person. Our last three cars were purchased from this dealership and we will happily do that again next time

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.

We had a great experience with this dealership! I highly recommend using Jeremy Tabangay as your salesman. He was very polite, and wasn't aggressive in his sales tactics. He really made you feel like you weren't just a number to him. He also did a follow up after we purchased, just to make sure that everything was going well. I would also like to give Matt (finance department) a good review. He was fun to work with on the financing of our vehicle, and didn't pressure us into buying any add ons. He was also very quick in getting all the paper work filled out. We really enjoyed our entire visit there. I would use this dealership again in the future. Especially, if I was working with both of them.

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
