I just had my 2016 Silverado serviced 2 weeks ago. I am very happy with all of the work that was done. Scott Goral is an amazing service rep and is great at communicating at every step of the way. He did a great job of making sure the warranty company cover everything that it was supposed to. Because Everything went so smoothly, I will definitely return to Mastri. a for future service! Thank you very much!

This is my 2nd vehicle with Mastria and I can't say enough great things about them! Tyler was great to work with and went above and beyond finding me the car I wanted. The ease of leasing the new car is something that will keep me coming back as a loyal customer. Their service department is also great and very informative. Thank you Tyler and the Mastria team for making this process a seamless one and super easy!

Mike was absolutely amazing. I’m excited to bring my business here.

Best purchasing experience! Jamie in sales was knowledgeable and professional and Steve the finance manager was absolutely the best. The finance piece has always been painful and this was the exact opposite. Very experienced without pushing unneeded options. Can’t say enough here!

Virgil got me in earlier than my scheduled appointment. I had oil,filter and tire rotation done.i also had brakes checked .Everything went great.As always great service! 👍

Google Apr 13, 2022

Perfect experience from beginning to end. Adam Medeiros, the Internet Sales Manager, took our initial call, answered our every question, made sure the vehicle we were interested in was still available, and was very courteous, pleasant, and knowledgeable. His professionalism convinced us to come in for a test drive. After driving the vehicle and deciding that it was exactly what we wanted, Jamie Lynch made our purchase experience easy and painless. (I wish every Product Specialist was this nice!) Steve O'Donnell was pleasant and took the headache out of the finance process for us. (Honestly the best experience I have ever had financing a vehicle). I can genuinely recommend Mastria for a great car buying experience. They definitely top my list if we ever need to purchase another vehicle.

Google Apr 12, 2022
