Our Reviews
Nathan and Meghan were great to work with. Even though the original vehicle was no longer available we able to work out a deal on another vehicle and still stay within my payments. I have been looking for a GMC Denali for over 3 months and they got the deal done. Truck was delivered on time as promised with a full tank of gas!!
Love this service department. Very honest always and Jessica and Scott are professional and very knowledgeable about any issues you are having with your GMC or Cadillac.
I brought my 2021 Caddy XT5 for service. Virgil was great at checking me and advising me about the service to be completed. Previously my 2019 GMC Canyon truck was serviced, although I was unhappy that it was not covered by warranty with only 29k miles on it the staff was good and professional.
Great service at Mastria!
Nathan is the go to salesman he’s honest compassionate and listens to your needs and wants in purchasing your car. I had a wonderful experience dealing with Nathan and Mastria dealership I wouldn’t change a thing 😊 love my Audi 🥰
If you're in the market for a new or used vehicle, I highly recommend Mastria! From the moment we walked in, everyone was welcoming and genuinely helpful. Our salesperson, Sayed Ahmed, was absolutely outstanding. He answered all of our questions patiently and never pressured us into making a decision. Throughout the entire process, he kept in great communication and provided timely updates on our vehicle. I typically dread car shopping because so many dealerships focus only on closing the sale, but Mastria was a completely different experience. They truly care about making sure you're comfortable and confident in your purchase. This was by far the best car-buying experience I’ve had! I will be telling my friends and family to buy their next vehicle at Mastria.
Sayed was very professional and helpful making my first time buying a used car solo very smooth!
Sayed was extremely helpful and great to work with; He took his time explaining things and was very patient with us. l definitely recommending asking for Sayed he was very polite and knowledgeable. I will definitely be going back to work with Sayed in future. Thankyou Sayed Keep up the great work!!
Had a good experience! Staff were knowledgeable and friendly. I had an overall inspection of my vehicle (2019 Cadillac). While waiting I received a short narrated video showing/explaing what was done and should be replaced/fixed on vehicle.👍🏼 This was VERY helpful! Will be returning for services! Thank you Jessica/MASTRIA GMC!
I just purchased a new vehicle. Isaiah Nieves worked hard to make it fast and easy. I had one issue with the car that he quickly responded to and corrected for me. He is great to work with and I will happily purchase another vehicle from him in the future.
From the moment I walked into the dealership, Sayed Ahmed delivered a level of professionalism and attentiveness that far exceeded my expectations. His depth of knowledge, keen attention to detail, and sincere dedication to customer satisfaction made the entire car-buying process not only seamless, but genuinely enjoyable. Sayed took the time to carefully listen to my needs, offering thoughtful recommendations without ever being pushy. His transparency and integrity instilled immediate trust—qualities that are all too rare in the car sales industry. Every step of the way, he communicated clearly, answered all my questions with patience, and made sure I felt confident in my decision. It’s clear that Sayed takes great pride in his work, and it shows in the way he treats his clients. I am absolutely thrilled with my purchase and grateful for the exceptional service I received. If you’re seeking a polished, knowledgeable, and truly customer-focused sales professional, look no further than Sayed Ahmed. He is a credit to his profession
