Used GMC Sierra 3500 trucks for sale near Windsor, CO

The staff was very friendly. They are low pressure and extremely helpful with all the questions I had. The sales guy I dealt with (Daniel) was great and I would definitely recommend anyone go see him.

I have bought two promasters from these guys in a bout six months time. As a business owner I don't have much free time was able to get in touch with Jeff Hale and put the ball in his court. It was the easiest purchase iv made I spent maybe 1 hour each buy at the dealership just to shake hands sign pick up and out the door ! No hassle got what I wanted for the price I wanted even a little cheeper. Will keep my business here!

Great experience. We've bought a lot of cars over the years and Dellenbach is the best in the business. Not your typical dealership. No pressure, good prices and really, really nice people. I would highly recommend.

Great vehicle for pulling my fifth wheel RV which weighs around 20,000 pounds. This dually truck pulls the RV very nicely without any significant strain on the engine or the transmission. However, like all of today's diesel engines there are 4 different system of emissions on this truck. Each one of these emission systems has sensors associated with them. If one of these sensors goes bad the truck will not perform optimally and sometimes it will go into the limp mode. Unfortunately this is not unique to GMC trucks. All manufacturers are battling this system. Also, I have had to take the truck to the dealer for computer upgrades in order to improve performance. I wish these upgrades could be performed on line (through wifi or with my own phone service). It sure would make things a lot simpler and improve the through put of the dealers who are already strained because of the limited number of available diesel mechanics.

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

Comfort, ease of driving, style, convenient for work and we LOVE the tailgate! Great for towing our heavy fifth wheel and our dogs are riding in style!!

Kerry was awesome and provided me a great purchasing experience. I would definitely recommend this place to anyone who is in the market for a new vehicle.

I ordered a 2022 3500 SRW Pro LB Double cab 4x4 in silver metallic / blk cloth. Added preferred package; gooseneck pkg; X31; upgraded wheels; camper/Snowplow prep; black steps. Got the 6.6 gas L8T. No start/stop and runs on all 8 cylinders all the time. I Love this truck. Had Rams and Fords in past. This is my first GM truck. I am in my 50s so not a brand thing... just a great truck. It was delivered in June. Truck rides great, tows very well, reciever or gooseneck. Fuel mileage is outstanding! Especially for a 4x4 one ton. I get 16 to 18 highway when not towing. I was shocked by how well it did and impressed with towing mpg as well. I generally tow between 6 and 14,000 lbs. Loads include a Glacier bay catmaran boat, 30' camper, and 3 axle 25' gooseneck. Truck easily handles those loads. The L8T engine is smooth and powerful. The 6L90 Transmission functions perfectly. If something were to happen to this truck I would not hesitate to order an exact replacement. So far very satisfied. MSRP as ordered was $53,945.

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.

Has a really Big feel to it. I currently use mine to pull gooseneck trailer. I haven't had a load yet that I couldn't pull. The downsides to this truck is to me I feel it could get better fuel mileage. Also I had trouble with #4 injector...dealership replaced it. Now my AC doesn't work all the time. Although it sounds like it's blowing it isn't.

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

It is a strong reliable truck and I would likae to have one for myself as a work truck and hauling heavy equipment like a man lift and compressor and still do some light duty work

no high pressure sales flew in from 550 miles away they picked me up checked pickup out and drove it bottit and came home with it 550 and no problem on the way home i .

An overall nice truck but for a person at my size(5,11) the mirrors and posts really block the view. My tinted windows really amplify the problem. The hood also takes a bit of room for a short person. Its a comfortable ride and works well in my line of work in excavation. The sound muffler in the hood makes you think something is wrong but apparently its not.

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

The Texas Edition combined with the X31 package and premium SLT makes a very nice combination. The Sierra 3500HD gives you a luxury interior and ride with all the capabilities of a great pulling truck. The Duramax is quiet yet powerful. It is no doubt the best of trucks for 2020.

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

Super knowledgeable staff. Easy to work with. Easy to talk to. No pressure what so ever. They work with your budget and get you the bottom dollar! Thanks again Country Truck and Auto!

Best truck I have ever owned. Used to tow a heavy RV. Wonderful comfortable ride. Highly recommended this truck. I drive it as my primary vehicle.

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.

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

Just what I was looking for and the price was right. The color was the same as the truck I traded in. We have purchased a bumper pull camper and now mountain passes will feel like flat roads!!

Buying a vehicle is never fun, but Jordan at victory motors has been outstanding. From his honesty to his communication, he has made this process super simple! I promise you, they are great.

It does everything I need to do and then some. Its comfortable and enjoyable. One of the nicest work trucks I've owned. Thanks to the people I bought it from.

Nicest truck I have ever owned preforms great with my RV Truck is comfortable and still works great when you need it to preform. Ride is nice and very roomy for all that want to travel with me

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.
