Used GMC Sierra 2500 trucks for sale near Frederick, CO under $450,000

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!

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!

Amazing! Always such great service. The staff is wonderful, so friendly and kind. I went for an oil change and they were so quick and efficient.

Love my GMC. Owned a Chevy and this absolutely beats it hands down. Never had any issues. Inside is very comfortable and can't imagine driving anything else

They did a great job of helping me find the perfect pick up. Levi spent a lot of time helping me. A very good experience. After the sale, I had a small issue with the battery and they swapped it out for a new one, no questions asked. Great dealership!

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.

Oryn Orozco has been extremely helpful, knowledgeable, professional and very patient. He has been wonderful to work with and has found me the perfect RAV4 XSE hybrid. Can’t wait for it to arrive!

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!

Great buying experience except for the finance process, which took way too long. The vehicle itself was recently serviced and new Michelin LTX M/S

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.

Professional from the start and they were not as much pressure as so many other dealers.

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.

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.

This is the first diesel I have owned. The power is amazing and I really like the room inside the cab. This truck is a beast... Love it!

Rafael H was very attentive to what we were looking for in a clean used diesel p up . His assistance in our purchase with our purchase was very good . professional, not pushy Gerald & Kay Schreiber

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.

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

Great service, great product as announces. All carfax reports where presented and added warranty as I requested.

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.

Great car great staff they made u feel like wanted with no b.s straight line service. Thank you will do more business later down the line

I was in need of a new car . The one i had was bought in 2005 but the year of the car is 2001. I wanted something a bit newer and affordable. I didn't catch the guy's name since my dad was the one who dealt with him first. No pressure at all. He was very helpful. I test drove the car and loved how it drove along with it's a big upgrade to what i had. So decided to buy it. I bought a 2012 Infiniti G25x, leather seats, AWD. front seat heaters, sun roof, backup camera, defrost on the side mirrors and it's a V6. I love it. I highly recommend buying a car here.

My husband and I were so overwhelmed with our car search and were worried coming here may be just one more example of the sleazy used car salesman trope--we could not have been more wrong!! Joseph listened attentively to what mattered most to us in functionality, comfort, and price, and helped us to find many options that would be a good fit for us. We had a list of some we were interested in and he recommended some others that would fit the ticket well. He was so patient and informative as we test drove countless cars! Seriously, this guy is like a walking car encyclopedia! But also, isn't afraid to look something up if he's not sure, which rarely happens. It felt like car shopping with your cool uncle who knows everything about cars and is looking out for you. Can't recommend enough asking for Joseph when you need your next car!! He can pull almost any car from another Autonation location, so it's worth going here to work with him even if it's out of your way or doesn't have the car you think you might want! We wound up not finding our vehicle within the Autonation inventory, but still wanted to go out of our way to leave a review for Joseph because he made that much of an impact! A great ally in the stressful, overwhelming process of a big purchase :)

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

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

Kirk listened and answered my questions about the car. He confirmed what service was needed after inspection and testing. Kirk was friendly and professional. I appreciated his great service.

Thank you Russell King for being professional, and accountable, by standing behind the cars Carmax sold us. Thank you for dealing with our issues in such a professional manner. We are now happy Carmax customers!

Very good experience made the process easy left with a new car all the workers are great!

I love my Denali. Beautiful truck inside out. When I drive down the road all heads turn. I couldn't have made a better choice. That's Cortez for you good service.

Dan Johnson and Nolan are amazing! The got me the equinox I wanted at a price I could afford! Thank you so much!! My heart is happy!

I had a great experience at this dealership. Joey, our sales representative, was friendly and attentive to our needs. The facility was clean and well-maintained, making the overall experience very positive.

This truck would help me thru out my needs I and my family love this beautiful truck, there is no better place for me to shop than the Paso Robles Chevrolet I highly recommend them
