Very honest with timely replies.
Very honest with timely replies. Pointed out vehicle deficiencies to me instead of letting me drive out from east coast to find out. I appreciate that increasingly rare quality. Thank you.
Happy Customer
I drove to Crown Buick GMC after making an appointment with Tammy Wagner. She was a new sales person. Tammy is very patient. She enjoys people and made me feel comfortable. I had alot of questions about my new All Terrain Truck. When she didn't know the answer- she was honest. (thats important to me) They , Tammy Wagner and Mike Mathis her manager sold me the truck of my dreams. I plan to be a life long customer with Tammy Wagner at Crown Buick

2020 GMC 2500 AT4
This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Everyone from the sales rep.
Everyone from the sales rep., sales manager, finance manager and shop team worked to make my experience simple and left a lasting impression. I will absolutely recommend this dealership to anyone in the market for a vehicle.
fowl like a locomotive
We use our GMC Denali 2500 mostly for towing our 7,500 pound travel trailer. A big factor in high ratings is the diesel. With the tow/haul mode engaged, the mountains of north Georgia and the Smokies were no problem. Especially liked the exhaust brake on the long, steep downhills; it kept the rig totally safe under all braking conditions. We tow at 60 and get about 14 mpg with no headwind. If you tow campers or fifth wheelers, you know how good this is. We don't have the navigation screen, so the rear view camera appears on part of the rear view mirror. The image is small for hitching up; still need a spotter. The 2014 may not be as quiet as the upgraded 2015's, but noise is never an issue, and the Bose system sounds terrific. Just be really careful parking a crew cab with standard bed at Walmart......
