Sales consultant Cesar Rincon was very helpful and

Sales consultant Cesar Rincon was very helpful and knowledgeable, he was supportive of my needs and provided all options to me. Finance manager Ryan Beavers was quick with the paperwork, honest and upfront with options and made the financial decision an easy one. Automotive Product Specialist Rogan Taylor was the cherry on the cake. He is very knowledgeable about GMC products, walking me through setup and how to properly use all of the options my vehicle had. Everyone at Castlerock GMC was wonderful to be around and made the process delightful. Thank you all so much, this will be my first stop for my vehicle’s.

Hola! I was born and raised in Chihuahua, Mexico and moved to Colorado when I was 7. I fell in love with Corvettes at a young age which is what lead me to want to work for Chevrolet. I pride myself on my extensive brand knowledge and make it my goal to provide each of my clients with exceptional customer service not only during the transaction, but long afterwards as well. I'm an avid golfer, enjoy mountain biking and off-roading in my free time.

I reached out to Castle Rock Chevrolet from Montana,

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 was raised in Cocoa Beach, Florida and moved back to Colorado with my family when I was 11. Growing up in a family of racecar drivers, my passion for vehicles started at a young age. I love that my job offers me the opportunity to meet new faces and make lifelong connections. I love country music and spending time with my two cats Benny and Rusty!

STAY AWAY FROM THIS PLACE!

STAY AWAY FROM THIS PLACE! I would’ve never bought from this dealer if I knew what I was in for. My experience has been nothing but a hassle. A car I’ve been looking for finally popped up here at a decent price, so I went in to buy it only to be sat in an office for awhile. A manager comes to me telling me they “priced the car wrong” and tells me the price isn’t actually 21k, it’s 32k and that it was allegedly a “computer glitch.” I don’t understand how a price difference that large wasn’t caught, especially when one of their sales reps reached out to me that morning with the price of the car being 21k. We ended up compromising a deal for the car (although I’m still paying way more than anticipated coming into this situation.) When I picked it up they reassured me that it passed a mechanics test, which was clearly xxxxxxxx. Had the car for 3 whole days before the check engine light came on. I call my sales rep who tells me to bring the car in and yet they refuse to provide me with a loaner car when I just spent several thousands of dollars with them and already had a bad experience. I explained I live 45 minutes away and my dog will be actively in surgery that day and I need to pick him up. Still denied a loaner car. So, I decide to take it to a Kia dealership. I then find out that they sold me this car with a known recall on my break system without fixing it before selling it to me, putting me in danger, and that this is unrelated to my check engine light. So not only do my breaks not work correctly and they sold it to me like that, but something is possibly wrong with my engine as well and they aren’t even offering me a loaner car in the meantime if I bring it in. Left several messages for the manager Luke King and have been unanswered. Absolutely horrible experience. Will update if a solution is offered.

5 Stars!

5 Stars! Exceptional Experience at Castle Rock Chevrolet GMC I recently had the pleasure of purchasing a truck from Castle Rock Chevrolet GMC, and I couldn’t be more impressed with the entire experience! From the moment I walked through the door, the professionalism and dedication to customer satisfaction were evident. The team at Castle Rock went above and beyond to ensure that my purchase was not only smooth and seamless but also affordable. The management team took the time to listen to my needs, answered all my questions with patience, and worked with me to find the best financing options. They truly made sure that I felt valued every step of the way. What really stood out was their attention to detail and the genuine care they took in making the entire process as stress-free as possible. No pressure, just top-notch customer service, and a true commitment to getting me in the perfect vehicle for my needs. A special shout-out to my fellow veterans – if you’re in the market for a vehicle, this is the place for you. The staff here truly understands the importance of serving those who have served, and they go above and beyond to make sure you have a positive experience. I couldn’t be happier with my new truck, and I highly recommend Castle Rock Chevrolet GMC to anyone looking for a fantastic buying experience. They are the definition of professionalism, and I’ll be a customer for life! Thank you, Castle Rock, for making my purchase so easy and enjoyable!
