Happy Customer
Just purchased a new Telluride. James Myrick made the purchase quick and painless. Everyone I was involved with throughout the process was friendly and professional. I got a deal I could accept and left happy with the process. I haven't used the service department yet but I've been told they're very good.

Great dealership.
Great dealership. Very nice employees in Service Area. I purchased my Buick LaCrosse in August 2019. I requested specific items such as less than 1 year old, low mileage, color and they located one in GA. Have had great results with it and still driving it.

Billy Ray Taylor Auto Sales - Salesman was K.C.
K.C. (Kyle) was very helpful and explained the purchasing process very simply and matter of factually. He was courteous and respectful and eager to do what it takes. I exchanged emails with him for awhile before going to the lot. I made an appointment with K.C. so he would know I was coming and be available and have time for me. K.C. had a couple or three trucks for me to look at that was based on my email feedback. The test drive process was very easy and quick (or as long as I wanted). Took about an hour or so to start the approval process but that was including my test drives. I was hoping to get it all done in about 3-3.5 hours and took about 4.5 but that was no fault of K.C.'s just the time it takes. I strongly recommend to use K.C. anytime you are looking for a vehicle. He will show you respect and no pressure.

Bought a used truck
Was helped by Mark Shaw, told him upfront don't waste my time and I wont waste yours. He didn't, traded in a truck and was out the door in about two hours total, pretty fast for a busy Saturday. The longest part was waiting on the bank to approve. Would recommend him to anyone looking to buy a used car or truck, he was very helpful.
