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

I had the pleasure of working with Brittany, who was very informative and a pleasure to work with.

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.

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 was here at the dealership a few months ago and I traded in my 2010 challenger on a 2014 challenger. The new one I purchased was an absolute gem. It only had about 600 miles on it. I thought “no way will this get approved” I’ll have to drive two hours back home without the new vehicle. Well I am pleased that I had Vincent and Kurt to help every step of the way. Between the two, they got me the best deal possible and I got exactly what I wanted. Never any pressure at all from anyone. The whole team there was exceptional to work with. I couldn’t have asked for a better car buying experience. Thank you to everyone. I definitely recommend going to Omeara. I will for sure be going back when I need to purchase another vehicle. Bill

Friendly and knowledgeable staff. Thank you for your help and we love our new car!

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

Found a desk area with electrical outlet the chairs were kind of old and banged up, and it was kind of in the vending area. Wi-Fi was good for working, but the coffee area was all out of packets for coffee. Good service and they got me out quickly through the process for an oil change the first one on my vehicle and the first service at that location. It was good the The cut customer service was good

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.

Great experience. Matt and Tony were great to work with. No high pressure stuff and pushing extras

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

Matt our salesman was awesome and listened to exactly what we needed along with Tony in finance we walked out with what we needed at the monthly price we asked to be at.

Gregory at Castle Chevy GMC is the automotive wizard we all need! When my wife’s 2023 GMC Yukon XL needed some TLC, Gregory didn’t just fix the issue—he played detective, keeping it an extra day to crack the case like a vehicular Sherlock. And as if that wasn’t enough, he sprinkled some magic dust on a couple of minor, non-essential fixes that were the cherry on top of this service sundae. Professional, communicative, and an absolute delight to work with, Gregory’s the guy who makes you wonder why all car repairs can’t be this fun. Highly recommend him and the Castle Chevy GMC crew for service that’s smoother than a Yukon on cruise control!

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.
