New and used 2025 GMC Sierra 2500 trucks for sale near Holly Hills, CO

Best truck buying experience ever. The sales team went above and beyond, and the finance department really helped us get the best rates.

I will admit, the first time my husband and I came to your dealership, we felt judged and we left. We took our business elsewhere and bought a new vehicle. Although it was a few years ago, there was still some hesitation to visit your dealership BUT I'm glad we gave it another chance. Our experience was great and that's because of the welcoming environment the moment we arrived, the friendliness of the manager and finance person but most of all, the awesome customer service provided by Adie Smith. Her professionalism and respect played a role in our decision making (it really did). Thank you for making us feel welcome and for the great service Adie. We will definitely recommend this location to friends and family AND we will buy from here again.

Great job. Timely service. Wonderful sales experience. Chuck was a great salesman. Thanks for a wonderful buying experience.

After researching various car sales service I found the service, guidance and communication with sales person, Robert to be excellent. He was an asset in searching the AutoNation inventory to find us the best match and value.

I drove right in, the Service Associate that greeted me was very polite and explained exactly what was going to be done, as I waited for my vehicle he came to check on me and asked if I had any other questions or concerns, it was a great experience and I will certainly be returning to Transwest GMC for all my service needs

We have pleasant experience with this dealership . We were looking for a new car checked and compared two cars and purchased one of them

My husband and I went in looking for a Jeep and Yami was very knowledgeable and helpful the hole transaction went very smoothly. We left happy with our new Jeep and excited for the summer to go on adventures.

One if our best experiences buying a new vehicle. Lot was clean, easily accessible and had available parking. Decent inventory of vehicles to browse and consider. Wasn?t approached by the ?hoard? of sales people. Only one sales person approached us, Tyler. He was friendly, knowledgeable and as low pressure as a sales person could be. Showed us various models after asking us our needs and wants. Did not try to move into the higher priced stuff. Even pulled two exact models with different exterior colors side by side so we could compare. Sales process, which usually is horrific, was pleasant. Some back and forth on rates and terms but not terrible. No high pressure from the finance office, no intimidation, no games. Actually enjoyed the entire process. Would highly recommend AutoNation GMC/ Buick West.

We bought a new GMC Sierra 2500, and our experience was fantastic, the sales Manager Julio was involved in the whole process and he explain everything that our sales person couldn’t. I recommend this place.

Good people work here and it's obvious that customer service is held at the highest standard. Never felt pressured and they were open, honest and knowledgeable about all my nitpicky questions :)

We were shopping for a new car. The whole process was a good experience from the beginning to the end. I would certainly buy from them again!

Kept me up to speed on the status of my repairs so I could plan my day(s).

The staff was friendly, knowledgeable and responsive. My issues were addressed earlier than expected. I was impressed.

Dave Singh was the tech representative handling the whole communication and repair on my vehicle. He was very professional and responded quickly every single time, I had to brong my vehicle from another shop which was awful and luckily Dave and Mike Marrone changed the overall experience. Keep up the good work!

My wife and I purchased a used 2015 Buick Enclave from Mike Maroone Cadillac GMC. We live in western Nebraska and saw the vehicle for sale on cars.com. I visited the Mike Maroone Cadillac GMC website directly and found the vehicle on there. There was a wide array of documents related to the vehicle right on the website. I was impressed with the transparency of the information that was offered. I was even able to access the vehicle’s Carfax right on the website. The vehicle was a one owner with a crystal-clear service record that had every single oil change, preventative service, and recall completed on schedule. Negotiations began though a series of phone calls and text messages. Our salesperson, Braden, was very nice and professional, but most of my contact during negotiations was with two of the sales managers, Andrew and Anthony. Both were equally transparent, straight-forward, and most of all very fair to negotiate with. Using only a total loss settlement we received from an accident, we had a limited budget to work with and they really knocked it out of the park! We drove out from Nebraska on Memorial Day weekend to test drive the Enclave and put the finishing touches on the negotiations. Everything went off without a hitch! Even though we paid for the vehicle in full that day, we still had to go through the finance office for all the sale documentation. Eric was fast and friendly, and we were on the road back to Nebraska by mid-day. Unfortunately, on the way home, we discovered an issue with the Enclave’s transmission. We were crushed and started panicking as to what to do. Used cars are sold as is, and we knew that going into the deal. We knew we couldn’t return the Enclave, so we drove it the rest of the way home. Brayden called us on Sunday to ask how we were liking the Enclave. I did not answer and did not return her call until Tuesday morning since it was Memorial Day weekend. I left a message for her explaining the transmission issue and that we were aware that it was sold as is. I then took the Enclave to a transmission shop and had it diagnosed. The Enclave needed a new transmission to the tune of $5,800, plus tax. I received a phone call from the sales manager Anthony and within 5 minutes he offered to pay for HALF of cost to replace the transmission! I sent him a copy of the invoice from the transmission shop, and I had a check in my hand by the end of the week! When I thanked Anthony, he told me, “Doing the right thing isn’t always easy, but we are always going to do the right thing”. Mike Maroone Cadillac GMC earned a life-long customer here and I will make that drive to buy from them again anytime! Thank you, Braden, Andrew, Eric and most of all, Anthony! You are all a class act!
