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

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.

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

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

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!

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.

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.

Jenny Rose is the best service advisor that we?ve ever had. She made sure that all repairs were completed thoroughly and quickly. We will continue to get our Tahoe serviced here.

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.

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

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
