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 had the recent pleasure of working with Kayla on the purchase of my 2nd truck from Prestige, and she was amazing. Made the buying experience great, which is not usually the case at a dealership. I would recommend going in and working with her to anyone looking for a new car. Thoughtful, honest, nice! Thank you Kayla!

3rd time buyer
I had a terrific experience dealing with Kenston now for the third time buying a vehicle. I highly recommend this dealership as they make the entire process very easy and low pressure. Matt was a terrific help to me answering questions and easing the buying process. I ended up purchasing a terrific truck, low miles and every bit as new as driving off the Ford dealership lot. Buy from Kenston, you won’t regret it.

The salesman we worked with was knowledgeable and personable. He did not try to strong arm us or pressure us into making a purchase. He provided us with a background on how the dealership ended up with the truck we were interested and answered all of our questions about it. This dealership's professionalism demonstrates why it is one of the premier shop's in New England. You can't go wrong with them.

I was greeted by a pleasant worker who told me where to drive to enter your service area. Next, another worker asked for my keys and told me where their lounge, restrooms, and coffee was located. She said she would get me when my car was finished. She was very professional explaining the consent form I needed to sign. I thought everyone really cared for their customers. The building was so clean, I was impressed with everything I saw.

There’s a reason people leave the Peters sticker on their car after they buy one and it’s because of the top quality customer service provider by the caring team at Peters. The online shopping experience was easy and fun compared to the pressure of our last car buying experience. Now our family fleet has Peters stickers!
