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 went into Corwin looking for a specific vehicle.
I went into Corwin looking for a specific vehicle. Bailey Reed approached me and I told him I was interested in a truck on the lot. He went the extra mile for us to get what we wanted. He made it easy for us, I appreciate him a lot, he did a good job for my wife and I. This is the second time we’ve bought vehicles at Corwin, it’s our go to place for an honest deal.

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.

Working with Drew at Briggs Nissan of Manhattan made the car-buying process remarkably smooth and stress-free. From our initial interaction, it was clear that this dealership operates differently—prioritizing genuine relationships over high-pressure sales tactics. Drew took the time to understand our needs and guide us toward the right vehicle, without ever making us feel rushed or pressured. In the end, we felt confident that we reached a fair and mutually beneficial agreement. Gabe in the finance department further reinforced the dealership’s commitment to a seamless experience, handling everything efficiently and transparently. If you’re looking for a dealership that values trust, respect, and long-term relationships, I highly recommend connecting with Drew at Briggs Nissan.

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.
