New and used 2026 GMC Sierra 3500 trucks for sale near Boulder, CO

Great car buying experience. Friendly, knowledgeable, no pressure salesman Kyle Berry. One minor problem was handled quickly and professionally with no hassle. Go see Kyle.

DJ was my salesman and he did an amazing job! I highly recommend going to Alpine Buick. The Facility is beautifully represented. Always eager to help.

Rafeal was my contact there and he was great. He went above and beyond to communicate share photos and video and was very transparent. As a matter of fact the whole process and everyone was easy to work with. Not the dealer where sale and sale manager go back and forth to do some crazy negotiating. Open transparent and fair dealing. Rafeal was an advocate throughout and in and out with anew car well less than an hr after trade in paperwork

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

We saw the car online a couple days before we could get over for a test drive. We scheduled the drive and the car was ready when we got there. We moved forward with the purchase and were pretty quickly out the door. The car was extremely clean for a 7 year old car, and all the vehicles on the lot looked clean. Friendly sales and finance staff.

Rafael H was very attentive to what we were looking for in a clean used diesel p up . His assistance in our purchase with our purchase was very good . professional, not pushy Gerald & Kay Schreiber

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.

We were extremely happy with Transwest GMC and will defiantly be buying from them in the future. They got us in and out very quickly and professionally.

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 had a great experience as a first time buyer from a dealership and my sales representative was extremely polite and very helpful in helping me purchase a vehicle that I liked.

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.
