Made an appointment for my malabou, dropped off night before they had a rental waiting for me I was dealing with Paul Goldstein, a hour later Paul called me with a diagnosis, I said ok didn’t have to use my extended warranty, the part was a recall Paul and the entire device was quick and awesome I will deal with Paul and Mastria again and recommend them to other people as well thank you
Brett was very knowledgeable. Spent all the time we needed explaining the whole car to us. He is very knowledgeable. He knew that car inside and out. We really appreciated the time he spent with us he is excellent. Thank you Brett for all your patience and all your knowledge 5 Stars
Michael Dube was so helpful and personable and trustworthy. We’ve been up the 44 auto mile before looking for a car and have had negative experiences with the car sales reps. However, when we met Michael and went into the Buick dealership it was a totally different experience. We knew right away that we were going to get a car from Michael because he was honest and absolutely love the Cadillac. It was just what we were looking for. Thank you for giving us such a good experience. We are so excited about our new purchase.
Friendly and low-pressure. We didn't feel like we were being sold by a salesman which is preferred. Brett was helpful.
This was the best car buying experience I’ve ever had. Great customer service, friendly staff. Our salesman, Michael Dube, went above and beyond to make sure all of our questions were answered and we had a positive buying experience a we never felt pressured during the whole process. Michael made everything as easy as could be, explained everything, great communication from the minute we walked in until pick up and continues to check in after to make sure we are happy. We will definitely return for our future car needs!
Michael Dube was excellent. He helped me every step of the way. The truck was in Showroom Condition when I picked it up.
I've been trying to work with a dealership local to me and recently went to Mastria GMC Buick and met with Michael Dube. I was very happy with my experience that I received from him. Very well versed on all the inventory especially the vehicle I was looking at. A true complete professional, allowing the car to sell itself without any sales tactics. Mastria should be honored to have him apart of the team.
I went with my cousin to pick up a car she purchase and her sales associate Micheal Dube was top of the line... He made sure the on star app was working also that she called on start and set it up correctly went in the car with us and explained all the apps on the car and features and buttons and what they meant also accompanied her to the sales department so she can order the accessories she wanted... He made sure she left there with no questions but if she thought of one gave her a card and told her to call anytime I do recommend him and next car I get might be at Buick Mastria.
I just bought a car today and Brett was so helpful and very nice! Made the whole process easy and stress free. Nicest workers and very nice dealership! 10/10 recommend!!!
I would definitely recommend Michael Dube. He went above and beyond to make everything go smoothly. He was very easy to work with and made the process simple and fast. Car is amazing!
Kerry was very helpful both over the phone and in person, he was very flexible with me to make an appointment and come in and answered all questions I had
Truly the easiest car buying experience I’ve ever had! Mike Davey was super helpful, took the time to help me find the perfect car in my budget. Buying my car took no longer than a week for me to have the keys in my hand!
Excellent time here. Was treated very well by Brett Kultgen. Deal was made very satisfactorily. Will recommend to friends and family

Brett, at Mastria GMC did such a great job for me. He was very patient and extremely helpful, helping me to make a big decision on my next car purchase. He was awesome to work with and I will be driving off in my new car real soon! Thanks Brett!
Kerry was incredible. Straight shooter.
I visited the showroom to see and test drive the Cadillac XT4. Michael D. was able to show me the XT4 and the XT6. Both vehicles exceeded my expectations for Buick GMC brands. The Sales team were very knowledgeable not only about these cars but comparable models from other car makers.
Excellent customer service. Salesman Kerry and Manager Patrick gave a very honest experience and they were always transparent with me. They provided excellent communication alomg with a stress free experience. Looking forward to going back to Mastria.

Brett was my salesman, he listened to my needs/wants out of a new truck. He located a vehicle that fit my criteria and we ended up making a deal together on it. Definitely recommend using Brett at Mastria for future car/truck purchases
