I'm always pleased with Mossy, but this time they went beyond all expectations. The issues I had with my vehicle was very challenging, but Mossy never gave up (a BIG THANKS to Jeff, he's the man). Mossy called in a GM engineer.....WOW. Problem solved! I tell you this dealership treat their customers like family.

Amazing experience!
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.

Curtis Gasper was super nice and easy to deal with and
Curtis Gasper was super nice and easy to deal with and didn?t pressure me. I got the truck I wanted at the price I wanted. Kirk Dominique in Finance was also super nice and did not pressure me to purchase add ons that I didn?t want, and he negotiated well on the ones I did want. It was worth the hour drive.

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.

Mostly always a heart breaker!
Mostly always a heart breaker! Have stated this many times before...to no avail! No initial person assigned to place a paper mat on your floor and collect your keys or move your vehicle to a unconscious location..no service rep to greet you with your request etc etc...
