Been purchasing auto?s from Louie for years! Super nice guy! Go see him for your next vehicle purchase!

I purchased a 2025 GMC that was used which was listed online. I got an immediate response when I texted and they were very helpful in providing information. I feel I got a good deal. They handled getting the vehicle shipped to NC. I’d highly recommend Crown and Brandy (sales).

Joseph Grego was a very helpful salesperson. This was our second purchase from Crown Buick through Joseph Grego and we appreciated doing business with him.

Amazing experience! Everything was transparent no surprises, was worried about the long drive and having the dealership change things up on me but no everything was perfect. My sales man really is a down to earth gentleman, he went above and beyond for me and really hit a personal level of trust! Kimble wright is a name I will never forget based on my experience at this dealership.

Hands down my best car buying experience. I will purchase my next vehicle with Crown Buick GMC.

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.

They took care of me in one day and surprisingly it wasn?t too expensive for what was done.

took a little while to locate the part but once it came in, installation was done to my satisfaction.

Cheyenne did an excellent job. She is very knowledgeable and her feedback helped me to make the best decision at the time of purchasing the vehicle. I highly recommend Cheyenne to be your sales person.
