Used GMC Sierra 2500 trucks for sale near Johnstown, 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.

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

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.

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.

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

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.

I recently purchased a car and was very pleased with the professional and knowledgeable service from my salesman Scott Halpain. He showed me how to work all the features on the dashboard and explained the paperwork to me. The rest of the people I worked with were also very helpful.

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.

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

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.

Cori was incredible. She was engaging, caring, patient and thorough. This is my 4th Volvo and she showed me more features and 'how too' then I have ever been shown on any previous Volvo. She also connected with us personally and was genuinely interested and caring in who we are and what was important to us. She also worked very well with the Sales manager as a team, and they both were efficient with time and helpful.

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.

Daniel V. Went in for an oil change, staff was super nice and attentive for both drop off and pick up! After arriving, it was nice that he had actually shook my hand and introduced himself. He helped me out a ton and was very informative and professional! We Had a few good conversations and laughs, then he walked me out to my car. It was a great Service, and I really appreciate Daniel for helping me out!

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!

I showed up. They had the car outside pulled right up front for me. Cisco greeted me and was friendly all the way through. I drove the car it drives great im a certified mechanic. It is in great condition. I get my tax returns next week. I will be back to buy the car if it's still available l. Based on the way I was treated even if the hyundai is not available which i hope it is but if not I will be back to buy a differnt car from South Creek

Love this vehicle. I feel safe transporting my grand daughters. It is reliable. It?s great on highway and city driving. I would recommend a GMC

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!

Greg Wolaver was a great help in regards to my long distance purchase of a used Jeep Commander. He was up front during the whole process and greatly assisted in the shipping process. I haven’t gotten my vehicle yet but if it’s half as good as he stated it will be a great purchase.

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.

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.

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.

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!

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've owned my truck for nine years now it is never once let me down. I'm about to put my first set a tires on it and brakes other than that I don't plan on getting rid of it it's never let me down and after reading all the other reviews it makes me realize they don't make them like they used to as they used too!

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.

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!

Raul, Derek and Alfonso made our buying experience simple! Found the perfect truck for our needs
