Used GMC Sierra 1500 AT4 for sale near Thornton, CO

Great experience buying my Tahoe from Greenwood. JS made sure my first time experience with them went exceptionally well. I highly recommend GWA for all your automotive priorities.👍

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!

Berkenkotter Motors in Castle Rock, Colorado and Parker are excellent dealers in used car, and truck sales. We have purchased our fourth vehicle (Toyota Tundra Max cab) from them in the last 12 years and love it. Berkenkotter Motors provide awesome, honest, low pressure used car, truck sales. They stand behind their vehicles if you have any trouble in the short term. Although they sell used cars, RV's , boats, and trucks they are checked over and are of great quality. I did get a great trade in on my 2003 Dodge 2500 long bed. Previously we also purchased from them a 2007 Toyota 4runner, and 2007 Toyota corolla. We had only one small service on the 4 runner. While having five lots, they have a lot of cars to choose from and if they don't have what you want they can get it in a short term. Take the time to meet their friendly staff, Dan, Steve, BJ, Alan, Frankie, Wade, jetty, Hanna, etc. We just love them. We got the financing every time we wanted. We currently are looking at RV's for our retirement travels.

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

The people there are very helpful, Had a check engine light come my truck and I was headed out on town the following day. They made room for me that day and got back on the road!

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.

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 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

Very good experience made the process easy left with a new car all the workers are great!

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.

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.

I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

Great looking vehicles and a large lot with a lot of options. Worked with Leon and we couldn’t be happier. Made a good deal on a great car and it felt like he really went to bat for us as the buyer. I highly recommend asking for Leon when you walk through the door.

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!

Kirk listened and answered my questions about the car. He confirmed what service was needed after inspection and testing. Kirk was friendly and professional. I appreciated his great service.

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 very pleased with the vehicle I was able to purchase at Grand Valley Auto Lakewood! I had less than perfect credit after being left carless in my divorce. My friends had recently purchased a car from Mike and Kelley and they assured me I would be treated honestly and fairly. I was very skeptical due to the fact that I had recently been taken advantage of on the purchase of my new TV. They listened to my wants and needs and I left in a car that I both loved and knew would do the job. I would definitely recommend and return for my next vehicle purchase!

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.

I reside in Arizona and bought a used 2016 M4 out of state from this dealership in Colorado and Chad Folkerts-whom I strongly recommend-,my sales rep, did an incredible job coordinating the entire process. I flew out for a test drive and walk around of the vehicle prior to signing and Chad was personable, professional, and had great communication both on the phone and in-person. I even made him jump hoops by having it pre inspected at the local BMW dealership. Also helped arrange getting the car shipped down here. I also had a great experience with Roman, their finance manager. He made signing quick and painless. I applaud the level of customer service at this dealership!

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?

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!!

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 car buying experience. Friendly, knowledgeable, no pressure salesman Kyle Berry. One minor problem was handled quickly and professionally with no hassle. Go see Kyle.

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.

Great People and love the atmosphere. Very helpful in any questions we had. Definitely would come back for my future car purchases.

Great performance, hard to clean, everything, I expected. Getting lots of compliments and head turning. Stomping with thee BIG DAWGS!!!! Good gas mileage on highway.

I had a great experience as a first time buyer from a dealership and my sales representative was extremely polite and very helpful in helping me purchase a vehicle that I liked.

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.

Brice and James were amazing? Best experience ever!

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.

Looked at more expensive truck with less options, bought the GMC SIERRA AT4 Turbo Diesel 6. I now only put fuel im once a month. And long distance trips are easier due to better fuel economy. One of my best investments ever.

Done on time. Warranty recall on the engine. Checked out, now with new 40/wt oil. Nice service bay, responsive staff. Showroom full of new cars.

Does anybody else’s truck just sit there after you put it drive? I have to bump the accelerator to have it go into gear. ??????????????????????????????????????????? ?????????????

Amazing experience. Cornell was outstanding. Finance manager was very nice and quick. Will definitely come back to do business with again

Truck meets my and my wife's needs. She loves her and I do to! Love sport mode and the tow hail mode. Rides like a Cadillac!

I was here at the dealership a few months ago and I traded in my 2010 challenger on a 2014 challenger. The new one I purchased was an absolute gem. It only had about 600 miles on it. I thought “no way will this get approved” I’ll have to drive two hours back home without the new vehicle. Well I am pleased that I had Vincent and Kurt to help every step of the way. Between the two, they got me the best deal possible and I got exactly what I wanted. Never any pressure at all from anyone. The whole team there was exceptional to work with. I couldn’t have asked for a better car buying experience. Thank you to everyone. I definitely recommend going to Omeara. I will for sure be going back when I need to purchase another vehicle. Bill

Excellent comfort and very good truck, it is very functional in every way, both for business and for personal, it can be said that I have the 2.7L Turbo engine and I can move up to 11500Lbs already checked by me

The team at Autonation West pulled together and handled a very unique deal I presented to them. Know that when push comes to shove the AW team truly negotiates fairly.

The features and styling are very aesthetic. The truck has very smooth handling and response. I am impressed with the response from the Diesel engine.
