Used GMC Sierra 2500 trucks for sale near Milliken, CO

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

The team was very friendly and helpful through the whole experience. I appreciate the attention to detail and taking the time to show me the features of the vehicle. Thank you!

I had dealings with Mr Lopez on buying my ride. If your looking for the "Spirited" ride, He's the man. Smooth, seemless transaction, upfront, explained some of those "details" on that paper work we all sign for the next ride. Lets not forget the "Paperwork/Contract" writers and the ones that make the "yeah, lets do it" decisions, kinda behind the scenes. Thanks to them all.

I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

Dee is a great salesman fast experience!! Would recommend to a friend or family member

What a gorgeous truck, runs good, sounds good and has all of the amenities I need although I am looking forward to their next interior upgrade.

This truck is everything I wanted! GMC, 4x4, Lifted, Low milage. It's going to be great for my hunting and 4 wheeling! I love it!

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

Great power and yet great economy. Love the safety features with the cameras and side vehicle warning. Camera that shows side of vehicle, including trailer when turn signal is on is great. Also appreciate the bed camera for hooking up gooseneck trailer.

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

One very awesome vehicle. Checks all the boxes you need in a truck and exceeds expectations on quality, performance, and looks great ,too. Love my nre truck.

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

Has everything we never knew we needed. Reliable and heavy duty. The bed is so convenient and we didn't have to chose between any options, this truck has it all.

Amazing experience .super patient and no hassle team, completely transparent Charles and Rick took good care of us! I would go back there again with my next purchase

Wonderful truck. Has had zero problems. I am trading for a new one. Truck is all original with no modifications. Truck is in excellent condition.

I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

My sister and I have been shopping for a replacement vehicle for our aging Chevy Tahoe. After several awful experiences with salesmen in various dealerships in Longmont I went online and found the perfect vehicle at Courtesy Mazda, a smaller dealership unknown to us. When My sister and I arrived we were greeted by the sweetest receptionist; welcomed by the sales lady, Aspen Swanson. Aspen was friendly, fun, easy to work with and in short order we had test driven the Tahoe, and agreed on the price. Another lady, Debra, in the finance department, was likewise wonderful, fast and efficient putting the paperwork together on the deal, and boom, we were done. My sister and I have both marveled about what a great car-buying experience this was and the comfort level we had doing so. Aspen went above and beyond to make sure everything was in order and worked closely with Debra on the paperwork. We left very happy and hope to be repeat customers in the future. Thank You ladies (and gentlemen) of Courtesy Mazda! It was a pleasure to do business with you all. The sisters of Loveland.

Great truck with a ton of room and a lot of compliments. Not gonna find a cleaner truck with only 44,500 miles on it. 20' inch rims with 35 tires on a 6' inch lift kit.

Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

Dan the owner and Greg the best sales manager I have ever worked with really .. Both of these guy went beyond helping fixing my 04 powerstroke .. No issues they got it rite in. Got it all fixed .. Thank you guys from the bottom of my heart.. I recommend everyone to buy from you guys !!! Thank you

this truck fits my needs better than the other 2500 models. Its hauling and towing performance along with its many people comforts will satisfy us for a long time to come.

This is now the third vehicle I have bought from them. They is never any pressure to buy and they give great trade in credits toward the new vehicle. They take the time to make sure that you are getting the one you really want. If they don't have it in stock they will find it for you. I wanted a black 3500, it took about three weeks and they found one I love. Thanks

I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

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.

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!

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!

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.

When looking at price point vise equipment, This is your truck. I looked at every 2500/3500 on the market, same vehicle equipment and price. I chose the Duramax.. HP, Torque of this Diesel, truck equipment that the SLT price point had everything that I wanted for safety, appearance and comfort, none other came close. This is your truck...
