So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

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.

From the beginning of my on-line purchase, Blake Harper
From the beginning of my on-line purchase, Blake Harper walked me through purchase procedure, explaining every question that I had. Although my chosen Yukon was (in transit), Blake kept me updated on it's arrival. When I arrived at ROYAL, Blake met my wife and I as we drove up. After a short time in the office, we were given a complete introduction to all the features of the Yukon, we took a ride on the road with Blake in the passenger seat introducing all the driving features to us that were new to us. I was absolutely pleased with our purchase and all the members of ROYAL AUTOMOTIVE!

Blake Harper made my experience buying a new car easy.
Blake Harper made my experience buying a new car easy. I financed part of it and was able to get a great interest rate. The application process was easy and took less than an hour to complete. Since I was trading in a car, I had to go home to get a few things that went with my trade-in. When I returned, they had washed, prepared, and filled my new car with gas. Everyone there was friendly and smiling. It's hard to believe they had the exact car, color, and accessories I wanted. Thus far, I am also pleased with the Buick Envista-Avenir. It's hard to believe that it has more hip room, leg room, and almost as much cargo space as my larger SUV, which I traded for it. It is quiet, rides very well, handles like a sports car, and gets impressive gas mileage. It's also easier for me to get in and out of it. I would call this a great trade!

I spoke to Mr. Samuel Wright. He was an amazing salesman over the phone. I will definitely be in soon with my Husband Eddy. He was very kind, caring, and knowledgeable. I never leave reviews for phone conversations, but the respectfulness of this young man, was expectational as well hard to find from a young gentleman!! Keep it up Bill Smith.
