I live in Utah but recently bought an Escalade from
I live in Utah but recently bought an Escalade from Halladay Cadillac in Cheyenne and honestly, I was just super impressed with everyone. You can tell these guys know how to treat people right and run a solid, honest dealership. They picked me up at the Denver airport and drove me up to Cheyenne. After the sale, on my way home I noticed that the USB and HDMI ports in the vehicle did not work. It was unexpected, but the way they handled it really meant a lot. The repair wasn't cheap but they didn’t make excuses, they just took care of it and made things right. That kind of service is rare, and it meant a lot. It was clear they stood behind what they sold, and that goes a long way. I’d absolutely buy from them again and recommend them to anyone who wants to work with good people who actually care about doing the right thing. Special thanks to Bryon the salesman who was super helpful and never pushy and John the sales manager who was a pleasure to work with in getting the issue resolved after the purchase and Shawn Smith the GM for standing behind the sale and being willing to take care of it. If I could give more than 5 stars I would.

Drew was there from our first call until we went home with a new Chevy. He worked hard to get us where we needed to be financially. Explained everything we needed to know about the vehicle we purchased. Drew was also there for some follow up calls, very patient and kind. We will definitely return for our next vehicle

I went in knowing exactly what car I wanted to test drive
I went in knowing exactly what car I wanted to test drive and had an appointment with Jean (John) Venant on December 27th. The car (2024 Mazda CX-5) was waiting for me when we arrived. Our salesman was a great guy & seemed knowledgeable about my particular vehicle. It didn't take me long to decide to buy the car on the spot. Baltimore in the financing department fought very hard to get me the best rate/deal available. They even gave me far more for my trade in that I was anticipating. Everyone throughout the (seemingly painless) process was great to work with. We felt very valued. My only "complaint" is the sticker shock I had when I saw all the "dealer fees" on the bill of sale. Many things (window tint, fabric protector, etc) were all things that you only typically see when buying a brand new car and not when buying a used car. And, with any used car purchase, I made sure to get the extended warranty. That's just smart no matter which dealership you buy from. However, I am concerned a bit to read very mixed reviews of the EasyCare warranty company, as it seems they only approve HALF of the claims submitted. Fingers crossed.

I drove over 1,000 miles to come to this dealership and I’m glad I did. They took care of us quickly and were very communicative throughout the whole process. They sent me pictures and videos so that I could know what I was getting even with being far away. Great group of people and very friendly and hospitable. Would definitely recommend this dealership. Thanks Staton for the easy car buy.
