Used GMC Sierra 1500 trucks for sale near St. Ann Highlands, CO under $899,990

I recently worked with Tyler and had a great experience buying my RAV4. He was professional, patient, and answered all my questions clearly. The whole process was smooth and transparent, and I appreciate his honesty throughout the deal. If you’re looking for a helpful and reliable salesperson, I highly recommend Tyler.

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!

Foundation Cadillac did it again—and honestly, I’m not surprised! When my 12V battery died on my Cadillac Lyriq, David Hann and his incredible team jumped into action. They did whatever it took to get me back on the road quickly and stress-free. David is truly amazing—always professional, caring, and reliable. If you’re ever in need of service, repairs, or even looking to make a purchase, go to Foundation Cadillac and ask for David. You’ll be in great hands!

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!

Had a great experience trading in my 4runner and getting a new tundra with Chris Williams yesterday! Couldn’t have made the process easier from start to finish and appreciate them staying late for us.

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 had the recent pleasure of working with Kayla on the purchase of my 2nd truck from Prestige, and she was amazing. Made the buying experience great, which is not usually the case at a dealership. I would recommend going in and working with her to anyone looking for a new car. Thoughtful, honest, nice! Thank you Kayla!

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 came to interstate Ford to have a recall issue taken care of. Mary Jo Fuletti helped me with that problem. I told her that there were other concerns regarding my F150 truck. She listened to my concerns and translated them so that her mechanical staff would understand what needed to be looked at. After an inspection, I was informed that there was about $5000 worth of work to be done. I have a Toyota warranty for the vehicle having bought it used from a Toyota dealer. Mary Jo had difficulty getting a response from the warranty folks but she was tenacious and got an inspector from the warranty office to come look at the truck and approve the work that needed to be done. Through Mary Joe’s and interstate Fords efforts, I had a total of about $6000 worth of work done with no out-of-pocket charges. I will definitely be back when my truck needs service or work. They have earned my respect and trust. I’m

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.

Thorton Location/ They were undestaffed but did a great job helping all clients did not close until finished. Kelly was our saleman, well knowledged and answered all our questions. David our finance rep did a great job about getting us the best deal. I would refer family and friends.

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

Elba me atendió muy bien! Encantados con el servicio, muy bien todo el proceso súper rapido

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.

Always a pleasure to get my truck serviced at Mike maroone Chevrolet, gmc, Longmont. Joe was my service advisor and got my truck in and serviced a lot faster then i expected. Service was an awesome. Thank yous

Excellent delivery of my new car. I love their new hybrid. would choose to buy a new car from them again.. the GM Mark was excellent

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

They were fair and responsive. Answered all questions. Speed of buying experience was best I’ve ever experienced.

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...

Our two Mazdas were total losses due to the Hailstorm that struck Cheyenne WY on August 1, 2025. I found AutoSearch USA through cars.com and contacted them about a Mazda CX-5 the had listed. Mike Blunn was great! They had just listed the car the previous Friday, and still needed top get some prep work done, but we set up a date to see it the following Tuesday. The car was not quite ready for us to take that day, so we made arrangements to meet at an Enterprise location midway between Cheyenne WY and AutoSeach USA's location so we could finalize the sale and turn in our rental. Everything went off without a hitch. I highly recommended AutoSearch USA for anyone looking for quality car buying experience.

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.

Everyone from the sales rep., sales manager, finance manager and shop team worked to make my experience simple and left a lasting impression. I will absolutely recommend this dealership to anyone in the market for a vehicle.

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!

Great car buying experience will be back for my next one just nice people and nice cars!!!

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.

Very welcoming gave us a tour of the entire place and made us feel at home! Very easy to work with on top everything else. Great deals are what got us looking but the sales service is what made the sale! Would definitely recommend

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.

Excellent salesmanship with Andrew. He learned exactly what I needed and wanted. Very happy with my 2009 C300 Mercedes! Perfect for me. Thank you.

We have owned our GMC Sierra 1500 for approximately 9 years now. The only real disappointment with the vehicle is that we had to have a full transmission replacement Just after the 100k mile without any warning whatsoever. The truck now has 107k miles on it and now , again out of nowhere, we are experiencing slipping in the trans and the engine light is now flashing. Very disappointing since we are starting to feel uncertain about the reliability of the vehicle now. The truck itself is gorgeous and shows ZERO signs of its age, sporting new rims and tires and a lifted body and no rust on the body at all. We hope there are no major issues with the engine as the vehicle has always been maintained as needed and on time for regular servicing at the dealership.

They were a pleasure to deal with and made the process of selling my car easy. They gave me the greatest deal available. I have earned their future business.

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.

My wife and I recently purchased a new car from McDonald Mazda in Lakewood. I’ve purchased 7 cars in my lifetime from dealerships, and this was by far the easiest and most satisfying car purchase I’ve ever made. Customer service was EXCELLENT, and even the finance manager (Johnny) was super easy to work with and not pushy at all. I was so surprised at how open and transparent everyone was with buying a car. AND it didn’t take countless hours to make the purchase. Yaay!! Our salesperson was named Santiago, and he was extremely helpful in answering our questions, and showing us all the details about the car we ended up buying. I was expecting some type of dealer fine print to pull the rug from under us, or some excuse about why the price was going to be higher, but everything was clear and accurate (I like to research cars before I even go to a dealership to look at them). We got way more than I expected for our trade-in, we were able to take advantage of Mazda’s financing deal AND special discounts, and Santiago even took our photo with the new car once we were done (and put it in a frame for us). Seriously?! I’ve NEVER had a dealer/salesperson come anywhere close to this level of customer service. 10-stars for McDonald Mazda, Santiago, and Johnny. You know they made a lasting impression because we still remember their names a month after buying our car! :-)

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?

Zach was the guy who helped me out very professional even tho I couldn’t get the car I wanted he tried super good people maybe here soon we can get me into what I want

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

The best dealer I have dealt with. Very nice will get you what your looking for out of vehicle open and honest.

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.
