Used GMC Sierra 2500 Denali for sale near Frederick, CO

Chris at Interstate Ford was absolutely amazing. He searched his inventory for a vehicle that I could afford. I would shop there again!

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.

Was looking to trade in my 2019 Raptor and found an Explorer Tremor. The deal was easy, fast and the salesman was very accommodating and knowledgeable.

Foundation has come a long way since a couple years ago. They follow up with phone calls about the status of my truck. And explain what repairs need to be done and why. They are not pushy but are courteous.

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.

Very nice and friendly staff. Excellent service. Explain and answer customers FAQ . They have different models and deals for every customer what ever your style or your budget.

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!

Everyone was professional and no pressure sales. A number very no nonsense dealership. I would go back to purchase again and would recommend to friends to go to Trans West GMC.

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.

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!

Carlos at Super Auto was professional, patient, and easy to work with. He addressed my concerns and showed me several cars without being pushy. I appreciated his approach.

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!

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.

Easiest car deal I have ever done. I have and will recommend them to anyone. I will be back the next time I buy another truck. Thank you guys. It was worth the 2 hour drive.

In August 2016 I bought a car. I found it online and contacted promptly by Patrick. Debbie in finance did a wonderful job. Communication was very good In February I needed to get my car repaired . The staff in the service department was very honest and Scottsbluff Nebraska patient with me. The service was great and fast

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!

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.

We were extremely happy with Transwest GMC and will defiantly be buying from them in the future. They got us in and out very quickly and professionally.

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.

They were a pleasure to deal with and made the process of selling my car easy. They gave me the greatest deal available. I have earned their future business.

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!

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 was so grateful for how kind and caring the staff here was when I went to go for my very first car purchase. I was incredibly nervous because I'm only 23 and I've heard horror stories about car shopping experiences for women, but they took such great care of me! They answered all my questions and were just genuine and honest with me throughout the process. The manager Chris gave me the validation and confidence I needed to finalize my purchase. I will 100% recommend this dealership to all of my girl friends and family because of the amazing experience I had here! Thank you Boulder Chrysler Dodge Ram for all your help in finding my dream truck!

I want this truck if I can't get help with finances I'll try againfri and ill have cash. I want it 100percent I've only dreamed of owning a truck like this and now if the Good Lord willing and the creek don't rise.a dream might come true.,!!!!!! I love everything about this ride.just rite for the open road.

Needed an oil change done fast. They worked with me and got me in and out and on with my day. Was able to keep to my schedule without any hiccups. Thank you!

I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

Very honest with timely replies. Pointed out vehicle deficiencies to me instead of letting me drive out from east coast to find out. I appreciate that increasingly rare quality. Thank you.

I drove to Crown Buick GMC after making an appointment with Tammy Wagner. She was a new sales person. Tammy is very patient. She enjoys people and made me feel comfortable. I had alot of questions about my new All Terrain Truck. When she didn't know the answer- she was honest. (thats important to me) They , Tammy Wagner and Mike Mathis her manager sold me the truck of my dreams. I plan to be a life long customer with Tammy Wagner at Crown Buick

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.
