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

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.

So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

Brice and James were amazing? Best experience ever!

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.

Great service department! Greg was great to work with. Very knowledgeable and great communication. Thanks

I had a great experience buying my Audi here! The entire process was smooth and stress-free from start to finish. The sales team was professional, friendly, and never pushy ? they listened to what I wanted and helped me find the perfect vehicle within my budget. The finance department made everything simple and clearly explained all the paperwork. The car was clean, well-prepped, and exactly as described when I arrived. I appreciated how transparent and efficient everyone was throughout the buying process. Highly recommend this dealership if you?re looking for an Audi!

Done on time. Warranty recall on the engine. Checked out, now with new 40/wt oil. Nice service bay, responsive staff. Showroom full of new cars.

Joey was great service manager...car service correct and prompt...very positive experience. Car was returned clean and with a full service report. Highly recommend dealership.

Austen is knowledgeable, efficient and friendly. I love that the tech sends you a video of your vehicle and what he?s working on. And the best of all is that they got me out in a timely manner

Yamile was knowledgeable, professional, empathetic and a terrific asset for you. She is a keeper!!! I could not be more pleased with the service she provided.

Our experience with Jason Montgomery was absolutely fantastic! From the very beginning of our car search, Jason went above and beyond to help us find the perfect vehicle. He was incredibly patient, knowledgeable, and genuinely cared about making sure we found exactly what we wanted. When it came time to go over our new truck, Jason took the time to explain every feature in detail ? making sure we understood how everything worked and felt completely comfortable before we drove off the lot. His professionalism, friendliness, and thoroughness truly made the whole process easy and enjoyable. We couldn?t be happier with our new truck or the amazing service we received from Jason. If you?re looking for someone who truly goes the extra mile, Jason Montgomery is the person to see!

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

Recently purchased a vehicle, and was pleased with customer service and straight forward pricing discussions. Our sales consultant, Starlynn and sales manager Tyler were great to work with. Thank you for such a positive experience.

I really appreciated the free service for my first time in with our new car.

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.

We arrived less than 60 mins before closing on a holiday. We were super impressed and we went home with a new car. It was after closing and more than one person was still there working. You don?t see that these days. Our car salesman even took a selfie with us.

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.

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.
