Service/Repair at Ray Brandt
I have recently moved to the area and have begun to use Ray Brandt Toyota. All of the personel has been courteous and professional. Much of my good experience has been due to Doug M. in the service department who made me feel my vehicle was being left in competent hands for the necessary repairs. When I am ready to purchase a new vehicle, I will use Ray Brandt as I feel the most important part of a purchase is the follow-up service one receives.
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

Courtney was hands down the best car salesman I’ve ever
Courtney was hands down the best car salesman I’ve ever dealt with. Super easy to talk to, upfront, and genuinely wanted to help—not just make a sale. They made the whole process way less stressful than I expected, and I actually left feeling confident and happy with my decision. If you’re looking for someone who keeps it real and actually cares, go see Courtney!

I'm so thankful to our salesman, Joe Grego, in helping my wife and I purchase a vehicle. We went in looking to purchase a new GMC Terrain, but it was above our budget. Joe made us feel comfortable and was patient with us in finding a 2023 Terrain in great condition and at our price point. I also want to thank the other Joe in the finance department. This was the first 'new' car purchase both me and my wife, so we had a bunch of questions. He was also patient and kind in answering all our questions. He helped us to be able to drive off in a beautiful vehicle that we could truly afford. Also, many thanks, to Joe Grego for capturing the moment by taking a picture of me and my wife in front of our 2023 GMC Terrain. He was thoughtful and respectful to ask our permission to post the picture on social media. We would not have that picture to look back on for memories of our first vehicle if not for him. I will certainly be going back to Crown Buick/GMC for any future vehicle purchases. I'll see you then, Joe.

Mr Kenneth Simms was the best Salesmen.
Mr Kenneth Simms was the best Salesmen. I didn't want all that normal Salesmen fluff. I wanted a car for my retired Mom who's car was recently totaled and I wanted it quick. I did my research, called with the exact car and my specs, and he LISTENED. He was patient, professional, and knowledgeable and above all accomodated our needs. Bottom line, he was selling a car and we were buying one. Mr Kenneth made the DEAL. Even delivered a car to my Mom in Gonzales, then met us at the dealership on his off day to deliver her actual vehicle. Thanks Mr Kenneth! God Bless.

Jason Payne definitely made the purchase process the easiest! My husband recently had back surgery, so we were able to do everything very quickly, all we had to do was sign papers when we got to the dealership!! We were at the dealership less than an hour! We will definitely be doing business with Jason Payne in the future! I LOVE my GMC Terrain!!!
