New and used 2025 GMC Sierra 1500 trucks for sale near Highlands Ranch, CO

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!

Service was as expected. The rep was friendly and kept me informed regarding the progress of my service. I am very pleased. Thanks

Jason and Ryan were absolutely amazing in the sale of my new hummer! They were very patient kind and accommodating getting me in a vehicle quickly and efficiently. Will be sending friends and family to them they are rockstars!

I dropped my truck off this morning for warranty work. Mike at the service desk was very helpful getting me in right away. Johnathon shuttled me back to my office and was very friendly and quick. The process was easy and efficient! Thank you

Easy in and out! Very happy with my experience. Sales man went above and beyond! Very happy with the service. Would definitely recommend them and buy another car someday

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.

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.

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

Kyi at Castle Rock Chevrolet is the best in the business. If I could give more than 5 stars I would. I came to Castle Rock Chevrolet from Montana carrying the weight of a terrible deal I’d been locked into by Mike Maroone Chevrolet. I was horribly upside down on my previous vehicle, thanks to a deal that should never have been approved in the first place. It felt hopeless… until I connected with Kyi. Kyi didn’t just help — he changed everything. He took the time to understand my situation, walked me through every option with honesty and clarity, and treated me like a person, not a number. Thanks to his determination, professionalism, and integrity, I am now driving a 2017 Cadillac Escalade Premium Luxury — a vehicle I absolutely love, and a deal that finally makes sense for me and my family. What makes this even more impressive is that we did the entire deal remotely from Montana. Kyi made it unbelievably easy and stress-free — constant communication, no surprises, and everything was handled with total transparency. It was hands down the most respectful and seamless car-buying experience I’ve ever had. I also want to give credit to Luke, the desk manager, who was the one that made the numbers work. He took a tough situation and made the deal make sense — without cutting corners or playing games. It was clear he genuinely wanted to help, and I’m incredibly grateful for the effort he put in behind the scenes. Kyi and Luke are the kind of team members who elevate the entire Castle Rock Chevrolet experience. People from any state should be buying their cars here. I would do it all over again in a heartbeat. If you’re buying a car from Castle Rock Chevrolet, do yourself a favor — ask for Kyi. You’ll be glad you did. Thank you both — you’ve earned customers for life.

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

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

I found the vehicle on the internet on Saturday and contacted the sales person to schedule an appointment to look at the vehicle on Monday morning. It was exactly as described with available car fax and all necessary information. I liked the Denali very much, purchased it and drove it home Monday afternoon. It was a very pleasant experience in every way. Matt and Tyler were great.

Great experience buying a new vehicle. Would purchase from again. They have a great selection of vehicles to choose from. This is a first class car dealership.

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,

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.

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.
