Mr Kenneth Simms was the best Salesmen.
Mr Kenneth Simms was the best Salesmen. I didn't want all that normal Salesmen fluff. I wanted a car for my retired Mom who's car was recently totaled and I wanted it quick. I did my research, called with the exact car and my specs, and he LISTENED. He was patient, professional, and knowledgeable and above all accomodated our needs. Bottom line, he was selling a car and we were buying one. Mr Kenneth made the DEAL. Even delivered a car to my Mom in Gonzales, then met us at the dealership on his off day to deliver her actual vehicle. Thanks Mr Kenneth! God Bless.

Destiny Bode did a fabulous job putting together my new purchase on a 2026 GMC Yukon Denali! I was traveling from over 7 hours away to make this purchase and Destiny did everything possible to make sure I was getting what I was looking for in a new Denali and even worked out my trade in through pictures that I sent. Great experience all the way around!

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.

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.
