Halladay GMC review
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.

David Scott Lee GMC is the best in the Biz. I have owned 6 GMC yukons over the past 20 years and the last 3 I have purchased from Scott Lee GMC. They have the highest level of customer service that I have ever experienced with any of the dealerships that I have worked with. They are my lifetime GMC dealership.

Lipscomb Auto Center review
Went to just look at new cars, Wrong idea!
Went to just look at new cars, Wrong idea! We met Dexter and he was the best car salesman I’ve ever dealt with. He wasn’t pushy, He let us look, and then he gave us a few cars to look at at what he thought we would like. Found a car in a matter of an hour. Went back the next day and boom it was ours. They had the fastest and the best system at purchasing a car, simple and easy no more back-and-fort smooth and easy and I would recommend Them hands down.
