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

Fantastic people, the process was so easy and stress free…I just stopped by on a Saturday over the 4th of July weekend just to look at a Hummer ev (I planned on Buying another Hummer I found online) and I left the dealership 3 hours later with a new car and new friends…I dealt with Charlie and Ryan, from the second I stepped on property and met the guys for the first time I felt like I had know them for years…I am a great judge of Character and there easy going positive personalities where very genuine and so authentic, it made me and my wife feel as if we where dealing with a good friend or family member that had our best interests in mind. From start to finish and even 3 months later I am still feeling the warmth from them. I will never buy another car from another dealership as long as Ryan and Charlie are there…AutoNation is Lucky to have them on there team and I am reminded of my experience every day I get into my new Hummer EV and I will continue to pass the good word on to everyone I encounter!!! Thanks Alpine Buick GMC

Very professional listened to my concerns made trading easy trained me on the features I am very pleased with the purchase and the individuals that helped me

Looked for a low mileage Acura TLX or TSX for six months and I found this car near me. It was nicely detailed and looked well cared for from the posting on Cars dot com. The sales rep called me very soon after my initial query. The entire buying process took an effortless one hour and I was on my way with the beauty,

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.

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

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!

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

After any serving of a vehicle taking it through your car wash before returning to customer. This might encourage more customer loyality. Oil change prices are too expensive. The expertise needed to do that job doesn't equalate to charging that amount.

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!

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.

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

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!

Was looking for a 2025 GMC Acadia Denali. Went to AutoNation and was met by Caden Noar. He was fantastic! Showed us the Acadia he had on the lot, gave us a test ride and answered all our questions. Not once, did he pressure us to buy but was more interested in answering our questions. After the test drive, we noticed a Buick Enclave Avenir in the lot as we were exiting the dealership. Liked the car looks and went back into the dealership to see if Caden was available to show us the car. We knew nothing about the car. He came out, gave us a test drive, answered our questions and then asked us if we would like to see another feature of the car, so out we went for another drive. Again, no pressure to buy and we parted. Over the weekend, we decided we really loved the car and called Caden on Monday to see if we could discuss the price and terms. Bottom line, we bought the car at the price we wanted. Outstanding service from Caden to the Sales Manager to the Contract/Finance Team!

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
