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

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.

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

Technicians are knowledgeable and trained on servicing my corvette. I get the same care I have observed at the Bowling Green, KY assembly plant.

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 dealt personally w Manny Rodriguez. He was intelligent, knowledgeable, honest and transparent. I applaud MM Chevy for hiring such an inspiring young man. Would go back again in a heartbeat!! I purchased a nice Silverado due to Mannys professionalism! Phil Bravo

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?

Customer service was great service department was great the only complaint that I have is when I have an appointment for 1:30 and it is two and a half hours later when they get finished do not understand why it takes that long when you have an appointment

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.

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.

Was a great smooth experience! Mike helped us out and gave us a great experience.

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

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!

It was worth the drive from Silverthorne to remedy a situation with a used Lexus GX460 that I acquired from WCG. The sales personnel were helpful, courteous, and professional and instilled confidence in me to return for future product and to refer anybody to go there for new or used vehicles and service. Ryan in sales and manager Derek got it done promptly which ended up being a faulty tire causing vibration at high speed. Also an honorable mention to Raul! Thank you all. I enjoyed the return drive to Silverthorne.

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.

T was wonderful to work with and made me fill comfortable and willing to complete the sale of my truck. Thank You

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.

We had the absolute joy of working with T while we bought our vehicle. T went above and beyond in so many ways - by coming in on her day off to help us out, adjusting her schedule to accomodate ours, being open and honest about the vehicle we purchased and the dealership itself - she was able to answer all the questions we had. We even had a small issue (no one could have known at the time of purchase) pop up a week or so after we purchased the vehicle and T was able to get it fixed for us, no problem. And - you know how buying a car usually takes all day? Not here. It took less time than any other place we have bought a vehicle, which is amazing. Thank you, T! You are the best!

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.

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!

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.

Great experience! When I contacted Weld County Garage about a used vehicle, Sales Consultant Miguel Orozco provided exceptional service. Due to my 1.5-hour commute from the WCG location, Miguel provided photos and videos of the vehicle so I could be sure it was worth taking a full day off. I later learned that Miguel had come in on his day off to assist me, a gesture I genuinely appreciate. Having visited numerous dealers in my search, Weld County Garage stood out as the most helpful, professional, and customer-centric. They were not just interested in making a quick sale, but in understanding what I was looking for and finding the right vehicle that fit my needs and those of my family. Unlike many dealerships, WCG encouraged me to take the vehicle to my mechanic for a pre-sale diagnostic check, and all details listed on/about the vehicle were 100% correct. Like many, I have never had a pleasant experience purchasing a used car. However, thanks to Miguel and Craig, the entire process was painless and drama-free, instilling in me a newfound confidence in car buying -- especially with the right dealership staff. Thanks for a great experience, WCG!

This dealership has a massive selection of cars- it's something to behold. I mean every type, make, model, and price. Overall you cant miss here

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 !

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.

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.

Jarrett Garcia did a great job getting me into a nice car, quickly! The trade process went much smoother then I thought which is great! Overall happy with my purchase!

Great truck, solid engine, comfortable, smooth, and it handles great for such a large vehicle. Get one and enjoy miles of roadtrips with all you can tow or haul.

The facility here is awesome- clean and big. They take great care of their cars and everyone was easy to work with. Very easy and honest

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

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.

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.

My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.
