Used GMC Sierra 1500 trucks for sale near Frederick, CO

Chris at Interstate Ford was absolutely amazing. He searched his inventory for a vehicle that I could afford. I would shop there again!

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!

Bought my new to me Ram from Mike White. He was patient and answered all my questions

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 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!

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.

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!

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.

Very good experience with O’meara VW buying a nice used Jetta. Quick fast deal without the usual back and forth time consuming runaround. Friendly courtesy call a couple days after to check on us. Thanks Karson, Elva and sales manager Steve. 👍👍

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.

We were incredibly happy with Eugene and the service department today! They were fast and did great work!

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.

We had a very clean purchasing experience. The salesman was very helpful and knowledgeable. We would recommend this dealership for those looking to purchase new or used.

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.

Professional, honest, knowledgeable. In and out quickly. TJ was great to work with. Highly recommend

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!

Drove two hours to purchase a car, and everything was just as it should be. Easy to work with, straightforward.

I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

So comfortable and easy to work with. Felt like it was exchanged between someone I have known for a long time. Very accommodating with my schedule.

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

I did not buy anything, but when I visited the dealership, I found the employees to be friendly and helpful. The salesman I worked with was Mark and he was very nice and responsive. Despite the fact, the dealership was extremely busy that day, Mark came and met me within a few minutes of my arrival he was able to juggle several customers at once and allow me to test drive the vehicle I was seriously looking at.

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.

After any serving of a vehicle taking it through your car wash before returning to customer. This might encourage more customer loyality. Oil change prices are too expensive. The expertise needed to do that job doesn't equalate to charging that amount.

Everyone at this dealership is a class act! Great service. Ask for Ed Rivas to be your lead salesman. He will treat you right and take care of your needs. Extremely knowledgeable and responsive!

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

Very nice and friendly staff. Excellent service. Explain and answer customers FAQ . They have different models and deals for every customer what ever your style or your budget.

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.

This is a very efficient crew from start to finish! We found a car on line and they met our schedule from start to finish to allow us to find the car of our dreams. Excellent value and we are so glad we found Tiffany, Mark and the entire crew. 100 per cent positive from start to finish. Thank you Dale and Nancy Reisbeck

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!

Repair was quick and well done. Greeted me when I arrived. Explained repairs. Took the time to check for and apply any updates as needed. Will be back.

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.

Great service and friendly atmosphere on the purchase of my new 2025 Ram 1500 bighorn

I truly enjoy every aspect of this vehicle except for the fact that to have my text messages displayed on the screen I have to use a cord and cord my phone into the vehicle. I can Bluetooth phone calls But I cannot get any messages to display without using a cord. For the truck being a 2019 and the price point of it that is absolutely absurd. Other radios that GMCsells has this feature. This truck does not.

I generally do not do reviews, but I feel I must express my experience with Valley Nissan in Longmont, Colorado. I live in Boulder and have been considering a new Nissan Leaf, after contacting several dealerships, I have to say that Valley Nissan was by far the BEST experience I've ever had with a car dealership. From my initial contact with Blake the Internet Director, outstanding communication, he respected my preference in the way I wanted to communicate, answered my questions quickly and directly. Once I arrived at the dealership I was greeted by both Blake and my sales consultant Leon, who had all paperwork ready to go for a quicker transition. Leon went over the car with me , answered all of my questions and was very knowledgeable; (this was very appreciated as this is my first electric car). This outstanding customer service continued with the Finance Manager Nate, he came out and introduced himself to me, explained the rest of the process and when I would be with him to finalize all paperwork. The thing that impressed me with Nate was, he did not try and sell me a bunch of products/coverage, he presented me with what he would recommend based on how I was purchasing my car-so refreshing! What a great team at Valley Nissan, I would recommend anyone looking for a vehicle to reach out to these guys! So worth the short trip from Boulder, this review seems longer than my time in purchasing my new car. Thanks Again to All, Weston Boulder, CO.

Good afternoon everyone, yes, I’m a lady and I’m an owner of a 2017 GMC Sierra 1500 Denali, it has a V8 motor fully loaded sunroof & also it has heated seats & steering wheel for the cold winter months & in those hot summer months you have A/C seats nothing better than that am I correct? It’s been times like that wouldnt trade for the world!! So for all you ladies who think BIG TRUCKS are just for men, go out there & buy one have them put on some electronic slide in/out rails & go out & show the shows the boss!! lol 😄 I’m out looking for a new one now either a 2500/3500 pearl white

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. ??????????????????????????????????????????? ?????????????

I have purchased a number of vehicles from this location under different ownership. The one good constant has been the service department and the service tech Dave Singh. Ask for Dave he will not let you down.
