New and used 2025 GMC Sierra 1500 Denali Ultimate trucks for sale near Commerce City, CO

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

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.

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!

Purchasing my new 2022 GMC Sierra was easy as buying something through the drive-thru. The salesperson, Chris Maneotis was awesome. He explained how my trade-in would go towards the purchase of the new truck and went over the financing and options. I would highly recommend anyone to work with Johnson Auto Plaza.

Brice and James were amazing? Best experience ever!

My experience was very professional and l am very thankful l went to Johnson Auto Plaza in Brighton, Colorado. My salesman Mark was very pleasant throughout my buying experience. I will be recommending Johnson Auto Plaza to friends and family.

Took my car (2013 Buick) in for service because of a rattle when starting the car. They took the time to listen to my problem and correct it. they were very patient listing to my issue and truly worked hard to make sure it was corrected the first time. they did a great job and i sincerely appreciated their effort.

The service was top-notch. I had a broken mirror and worked with Greg Mudd, who found me a great deal on a mirror, painted it, and installed it, saving me about $350. He was incredibly kind and responsive. It was a great repair experience when I had been anticipating a stressful one.

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.

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!

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

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!

The staff is courteous and friendly. They answered all of our questions and made the process easy. It was a pleasure doing business.

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.
