Used GMC Sierra 2500 trucks for sale near Denver, CO

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.

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.

Ryan, Jarret and Heidi always take excellent care of us each time when we visit for a service, with both of our vehicles. We do Mike Huffman, he was our salesperson

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.

One of the best buying experience I’ve had in a long while. Jeffrey was great. Had everything prepared for our appointment. The truck was cleaned up and ready for the test drive. Once we got back we worked on the numbers. They were close, but working with the sales manager we agreed on a very fair deal. And that’s what I appreciated the most let’s be fair with each other. The next day working with Preston in finance was also very pleasant, he worked his magic and got us a great rate with the bank. Overall experience was excellent! I hope I won’t need another truck for while, but if I do I hope the three guys are still working here. Cheers to them. Ask for Jeffery(sales).

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 was interested in a new GMC Acadia, specific features and model. Zac Taylor worked very hard to bring a vehicle from the Colorado Springs store. He had everything outfitted as needed, worked out details remotely, then delivered it to me in the mountains. I drove away a great new vehicle at an outstanding price point. Thank you Zac for all of your hard work during this car purchase!

Jay quickly found the car I looked at online. He was able to quickly get use in and out of the dealership all in the same night.

I have bought a lot of vehicles in my life time but this was by far the easiest and most pleasurable car buying experience I have ever had. I sent an email to the dealership around 1:45pm to inquire about a car, drove to the dealership at 5:00pm and drove home at 7:30pm that same day. Ricky in sales was amazing, easy to deal with, I told him what I needed and he took care of it without a bat of an eye!! I will refer anyone to this dealership and specifically to Ricky Pim. Thank you guys!! you are the best! PS - Finance guy, equally as great!! Jersey!

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!

We received excellent customer service by knowledgeable and friendly employees. They knew vehicle options and were focused on understanding our needs, wishes, and wants in our vehicle. Highly recommend this dealership!

Michael Ramstetter was great to work with. I highly recommend working with him and Mountain States Toyota. He was super helpful.

Could never buy another truck after owning this. I'm only getting rid of it cause I ordered a 2021. Hands down, this is the best of the best!!

I have been having my cars serviced by Auto Nation after buying them from Auto Nation. I have been so happy with the trusted service I receive here that I have purchased 3 Jeeps from them over the last 24 years.

Josh was patient and did a great job. We hope to see him on our next purchase. Asking to use 25 words for this review is annoying.

Sherry was easy to work with and made buying my truck hassle free. I would recommend this team to anyone.

Everyone from the sales rep., sales manager, finance manager and shop team worked to make my experience simple and left a lasting impression. I will absolutely recommend this dealership to anyone in the market for a vehicle.

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.

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.

My experience with Castlerock Chevrolet since 2020 one of the best. I appreciate their customer satisfaction. Puts their customers first. My car engine almost destroyed by an oil change of a place I used to get by cheaper but no more. Thank u again.

Helpful and kind, answered all my questions. Next time I'm shopping for a car, I will come to Luis. It's important for me to have someone I feel listens to what I need.

Great experience buying my Tahoe from Greenwood. JS made sure my first time experience with them went exceptionally well. I highly recommend GWA for all your automotive priorities.👍

Brought my tundra in for a recall software update. They did a great job and kept me informed. The automatic check in and appointment software the use kind of glitches. But no harm done I will return.

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.

John is exceptional. He’s taken a lot of time with me on my search.
