Used GMC Sierra 1500 trucks for sale near Frederick, CO under $1,000,000

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 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.

Really liked working with Bryan and Victor, made the process easy and helped me get a new car :)

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 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. 👍👍

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.

Juan was really great to work with! It was a smooth and painless process! Thank you so much, we would definitely come back again for our next vehicle!

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 !

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!

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

Service was prompt, thorough, and reliable. Makes me feel assured that my car has ben fully assessed; I can drive with confidence, problem-free until my next visit. Service rep kept me informed, was respectful & knowledgable.

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

I was stressing about whether to buy or not. After I decided, The the process was fine. Very pleased with my sales guy PHIL SMITH.

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...

A Big thanks to Santanna, the woman that did the sales. Jefry the manager. Also, a thanks to Gaby and Adriyanna. There is no other place to buy a car than Omeara ford, because of this awesome team! God Bless u and thank you.

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.

John was my salesman he did an amazing job. He was excellent at providing excellent service.

I needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.

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

Smooth ride strong motor decent gas mileage inside cab is loaded and very tastefully done along w easy access to knobs. Plenty of room. In back seat ! Aclassy looking Truck with a tacky looking owner!!

Overall, the experience of buying a used car was very easy. They had friendly staff. The area was clean. I did have some cosmetic repair and they took care of all that I would definitely buy another one from this dealership.

The truck Handel's well. Sluggish when in second gear and the transmission thumps mostly when shifting down. Started about 40k. The ride is nice and comfy.

Recently we purchased a Subaru Crosstrek from Flatirons Subaru in Boulder, Colorado. The dealership was very clean, well organized and made a good impression from the moment we entered it. The available salesman at the time we came in was Connor. He was very polite, professional, knowledgeable and mannered. He showed us several vehicles helping us to decide what to buy. If you want to buy a Subaru I definitely recommend Flatirons Subaru and also ask for Connor. You will not be disappointed. Unfortunately we had the displeasure to run into another person who looked very unprofessional. But the experience we had with Connor, convinced me to give 5 stars to this business.

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?

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!

Erik Anaya made our buying experience a pleasure. Everyone was helpful and knowledgeable. They have a great inventory and we never felt pressured to buy a vehicle. They helps us pick out a vehicle that met our needs. I would highly recommend Weld County Garage.

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.

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

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!

We recently purchased a 2023 F-350 from Erin in Loveland. We live in Evergreen [approx 75 miles away], Erin had our deal and all docs ready for us to sign. Felt very comfortable with ClearShift and would definitely recommend to friends and family! Worth the drive for sure!

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.

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

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.

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

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.

Great experience Diana helped me out a lot had an easy first time buyer experience drove of with what I wanted thank you Diana and Ethio Motors.

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
