They diagnosed, ordered a part and fixed a very annoying noise in my 2025 hummer ev. This is a quality dealer. Shortline in Aurora told me that noise is normal. They are horrible and don’t care about thier customers. Go to GMC in castle rock !
My GMC Acadia was in for a recall, which required them to keep the vehicle for most of the day. They provided a ride home and back, even though I wasn't a "paying" customer at the time.
Jonathon was great to talk to was very polite thanks again 👍
Johnathon the shuttle driver was very professional and polite. Made the dealership experience that much better.
Jonathon my shuttle driver was great! Very kind and personable.
Great experience! Purchased my Yukon Denali from Austin and he was amazing! Very friendly, knowledgeable, helpful , and just made the whole Purchasing experience great! Thank you Austin!!
Great experience dealing with Rick. He made the purchase easy and traded me with respect.
I reached out to Castle Rock Chevrolet from Montana, still stuck in a terrible situation from a previous deal I got through Mike Maroone Chevrolet. I was deeply upside down on my trade — it was a deal that should have never been approved. I honestly didn’t think I had any good options left… until I got connected with Kyi. Kyi completely turned things around. He took the time to understand where I was coming from, explained everything clearly, and gave me honest, straightforward options without any pressure. He treated me like a real person, not just a number. In the end, I was able to get into a 2017 Cadillac Escalade Premium Luxury — and for the first time in a while, the numbers actually made sense. What really impressed me is that we were able to do the whole deal remotely, without ever stepping foot in the dealership. Kyi made the process incredibly easy — he kept me updated constantly and handled everything with total professionalism. It was by far the easiest and most respectful car-buying experience I’ve had. Big thanks also to Luke, the desk manager, who worked behind the scenes to get the numbers right. He took a challenging situation and somehow made it work, and it was obvious he genuinely wanted to help. Between Kyi and Luke, the team at Castle Rock Chevrolet blew me away. I’d absolutely recommend them to anyone — even if you’re out of state like me. And if you’re thinking about buying, ask for Kyi — trust me, you’ll be in good hands.
I had a great experience at Chevy GMC Castle Rock. I worked with Austin, he did an amazing job and the entire process worked out how I wanted. Everyone I work with to purchase my GMC were very professional.
I was in a tough situation after a previous car deal that left me deeply upside down on my trade, and I didn’t think I had anywhere to go. Until I was connected with Kyi at Castle Rock Chevrolet. From the start, Kyi treated me like a real person, not just a number. He took the time to understand my situation, explained everything clearly, and gave me honest, straightforward options without any pressure. Thanks to Kyi, I was able to get into a 2017 Cadillac Escalade, and for the first time in forever, the numbers actually made sense. What really stood out to me was that we were able to complete the entire deal remotely, and Kyi kept me updated every step of the way, making the process easy and stress-free. If you’re considering buying a car, ask for Kyi — he’ll take care of you and make sure you get the best deal possible. I can’t recommend him enough! He is the Best in the Business.
I bought my 2017 Cadillac Escalade Premium Luxury from Castle Rock Chevrolet, all the way from Montana, and it was the smoothest car-buying experience I’ve ever had. I was seriously upside down on my trade because of a bad deal I got from Mike Maroone Chevrolet. Kyi and Luke at Castle Rock took the time to understand my situation and actually made the numbers work. No pressure, no games, just honest people doing great work. Kyi made the whole process incredibly easy, even remotely. He stayed in touch constantly, explained everything clearly, and treated me with respect the entire time. Luke worked behind the scenes and got a deal approved that finally made sense for my family. If you’re buying a vehicle — even from out of state — this is the place to do it. And ask for Kyi. You’ll thank me later.
The service department is great. The service writer Dominic was great. Very helpful people. I will continue to use them.
Mr. Eller was very happy with his drive and the shuttle driver Jonathan. He was very personable.
