We worked with Tyler and picked up our new car today! The entire team was great to work with!
Have been in the search for a 2019 Jeep Grand Cherokee for quite some time now and found one at Mastria Buick that seemed to be the perfect fit. Steve Bent was extremely helpful, as well as encouraging throughout my entire sale process. Bought the vehicle and drove it home the same day! Positive experience all around!
Steve Bent was fantastic and made the experience such a smooth process!

Excellent experience with Jamie Lynch. He was very helpful and informative. Always available through entire buying process.
Fast, efficient and Mike was great to work with.
Always the best every time I go. Staff is very pleasant. Even for an oil change. They all have a smile on their face. I’ve had my car for a little over 3 years and would recommend anyone to them. Salesman to service to parts thank you for everything. You don’t see this kind of service anywhere.
Scott Goral was the Service Advisor who helped me when I had transmission issues with my Acadia in April 2022. Nobody likes when their car needs a major repair but Scott went above and beyond and made a bad situation much easier to deal with. He took everything off of my plate; he worked directly with my warranty company, pulled a rabbit out of his hat to get me a rental car for the three weeks that my car was in his service center. Easy to talk to, answered all of my questions and explained things in detail so it made sense to someone like myself who is not very mechanically inclined. He went to bat for me when my warranty company pushed back about what they would and wouldn't pay for and kept me updated throughout the entire process. I have always been an anti dealership for repairs kind of guy but Scott is the epitome of the old cliché "treat people the way you want to be treated" and because of that I will be back whenever my car needs any services or repairs. Thanks Scott, I appreciate all of your help!

Jamie Lynch was friendly and responsive. Very smooth transaction.
My sales experience with Tyler was short and sweet
Bought my Encore through them and they were great. I have taken my car there for all its service since and have found them to be completely professional, thorough, and spot on when they estimate the time and costs. Highly recommend. My family finds the Mastria group across brands to be a good group to do business with.
Mike D was so helpful and amazing
