I received a great experience at AutoNation West. My sales associate was very professional, knowledgeable, and friendly. The whole sales team were very kind. I would recommend the dealership to family and friends.

The staff was friendly, knowledgeable and responsive. My issues were addressed earlier than expected. I was impressed.

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

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

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.

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

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.

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
