New and used 2025 GMC Sierra 1500 trucks for sale near Centennial, CO

I had a blowout tire. Thank You for your service Jason, staff for getting me back out the road.

I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

Best place to purchase a car ! Makes it easy, saves money, and eliminates headache. Bought an awesome 4Runner from H.M Brown and the experience was phenomenal

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.

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.

Muy buena con el se�or Jorge Castro muy bien atendidos y nos ayud� mucho a poder adquirir nuestra troca

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

We worked with Kyle Berry and he was so nice. He showed us the trucks we were interested in but was NEVER pushy. Kyle started the trucks to let them cool off before we did our test drive and let us go. Kyle was friendly, informative, knowledgable, and laid-back. We just never felt like he was pushing a truck on us. He listened to what we had to say and responded from there. I would HIGHLY recommend Kyle and Transwest Buick GMC Isuzu.

I was here at the dealership a few months ago and I traded in my 2010 challenger on a 2014 challenger. The new one I purchased was an absolute gem. It only had about 600 miles on it. I thought “no way will this get approved” I’ll have to drive two hours back home without the new vehicle. Well I am pleased that I had Vincent and Kurt to help every step of the way. Between the two, they got me the best deal possible and I got exactly what I wanted. Never any pressure at all from anyone. The whole team there was exceptional to work with. I couldn’t have asked for a better car buying experience. Thank you to everyone. I definitely recommend going to Omeara. I will for sure be going back when I need to purchase another vehicle. Bill

I had the pleasure of working with Brittany, who was very informative and a pleasure to work with.

Friendly and knowledgeable staff. Thank you for your help and we love our new car!

Arie and Jason were great! They made the whole car buying experience easy. They were both extremely knowledgeable and did not pressure us in anyway.

Overall, it was a very smooth process when I recently purchased my new Buick. The only reason I didn’t give five stars is because there were two documents from the finance department that were forgotten/overlooked that caused a little difficulty for me.

I dropped my truck off this morning for warranty work. Mike at the service desk was very helpful getting me in right away. Johnathon shuttled me back to my office and was very friendly and quick. The process was easy and efficient! Thank you

Kyle helped us and was fantastic! He worked was low pressure, willing to work with us and very professional! We highly recommend!!!

Ryan Bonino was extremely patient and pleasant, and he couldn?t have been more helpful. Michelle Spivey was knowledgeable and explained all our options in easy-to-understand terms. The entire car buying experience was smooth and we?re super happy.

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

I received a great experience at AutoNation West. My sales associate was very professional, knowledgeable, and friendly. The whole sales team were very kind. I would recommend the dealership to family and friends.

Awesome buying experience! Vinny Mahoney the salesman was great. He made the buying experience very nice. Continues to check-in with me to see if I need anything else or if I just have any additional questions. Chris Tucker the sales manager was a pleasure to work with and was diligent and patient in helping me get all the qualified discounts. Highly recommended this dealership.

Service was as expected. The rep was friendly and kept me informed regarding the progress of my service. I am very pleased. Thanks

Austin Ellenberg helped us find the exact Buick Enclave that we wanted. He was very nice to work with and patiently helped us understand all the new features on the 2025 car. His explanations of everything were excellent, and we appreciate his offer to talk with us again about any new questions that we come up with. We also appreciate that he had a new battery installed before we took possession of the car, since the previous extreme cold temperatures had run down the battery while the car was on the lot.
