This time around I was impressed with the service I received from my advisor Steven Coyne and the work got done in a timely manger. The work being performed was under a mechanical breakdown claim as well as my lifetime oil contract and I had no billing issues or any issues with the work done. Thanks Chevrolet LITHIA.

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.

It was by far the best experience of purchasing an automobile I’ve ever had. Very courteous and helpful. I actually went to GMC dealers in Va. and NC and they couldn’t help me get the SUV I wanted. Went to Cars.com and submitted 3 notice of interest to 3 different dealers and Zeigler responded within 5 minutes. No haggling and gave me a more than fair quote. Everything went smooth and finally heard from other dealers an hour or two later. Really appreciate the professionalism. Love my truck and it was delivered today! Thank you for all your help.

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.

Jody in finance was great. The salesman Brian was very knowledgeable. The manager Greg Mier was friendly and accommodating. I am very happy with the GMC Acadia Elevation. Just be prepared to hang out on YouTube learning about all the bells & whistles.
