New and used 2026 GMC Sierra 1500 AT4X trucks for sale near Platteville, CO

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!

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!

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

Annissa Medina has helped me so much taken care of everything for me and is always so sweet, understanding, and very helpful with everything that I’ve needed. Her communication skills and personality along with professionalism always reassure me that I am going to get the best service and make me feel like I am always welcomed.

Worked with Cosmin on a used Porsche Cayenne. Very friendly and professional salesman with a no-xx attitude. Didn't leave me waiting around excessively during price negotiation, and was willing to work with me to find a deal I was happy with. Finance was super quick and low-pressure, I didn't feel like I was being lambasted with upsells that I made clear I didn't want. Good stuff, Austin. Very respectful and professional staff, and I would definitely recommend doing business with these folks. Keep up the good work.

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.

Matt is knowledgeable and helpful. Rich was great at explaining the financing options. They even delivered my new car to me at the gym! I'm very pleased.

I have purchased a number of vehicles from this location under different ownership. The one good constant has been the service department and the service tech Dave Singh. Ask for Dave he will not let you down.

Sales and finance teams were extremely flexible and attentive, listening to my concerns and working to find solutions. They supported 2 different test drives when I had a concern about a specific driving condition, being extremely flexible working around my schedule. Cam, Austin, and Alec worked together to provide answers to all of my questions regarding financing and extended warranties. When a last minute issue arose on a Friday afternoon, their maintenance department obtained the part and swapped it out on a Saturday morning to allow me to pickup the car that afternoon. Communication was excellent, receiving 2 status updates that morning.
