My experiences with Hunter in the service department have
My experiences with Hunter in the service department have been great, he is very knowledgeable, very respectful and understanding, he answers all of my questions, and I always leave with a smile and confident that my 2024 GMC Canyon truck is in good hands! I highly recommend McLarty Daniel Buick GMC for all of your vehicles servicing needs.

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.

This is the second vehicle we have purchased from Royal
This is the second vehicle we have purchased from Royal Moore GMC, and once again it was the easiest car-buying experience we?ve ever had. From start to finish, the sales process was seamless, straightforward, and completely stress-free. We knew exactly what we were looking for, and there was absolutely no unnecessary pressure or back-and-forth?just clear communication and efficiency. They were incredibly accommodating with our timing and the speed of delivery. Omid oversaw the deal while Jeremy handled the sales side, and they worked in parallel to make sure our time at the dealership was kept to a minimum. Nathan in finance had everything prepared ahead of time, so the finance process was quick, smooth, and painless.

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.
