I've long held firm on the belief that car dealers are the lowest life form in society. The very epicenter of these multi million dollar enterprises is the service dept. This is where the perfect storm of increasingly more complicated cars and naive owners that think a dealership cares for anything except their money meet. My story begins with my 2019 Sierra needing a catalytic converter at just 110k miles. After looking around online I came across an aftermarket one, not knowing that most GM trucks can't use aftermarket, you'll have an engine light after this is installed but at least its drivable. I brought it to Mastria to have it diagnosed and sure enough it was the aftermarket cat and an O2 sensor. They were able to clear the light (and noted the new cat was welded in and they didnt know how to get it out, crackheads do it in under a minute in the dark with no special tools or lift) and I had to drive it for 125 miles for the ECM to reset so I could go for inspection. I did this and brought it back, only to be told it now needs tires. They never mentioned this days earlier when they had it. They gave me a quote for tires. I saved about $500 buying online and having them installed locally. In this time the engine light came back on. So I emailed looking for a quote on the OEM cat, which was ignored so I went in person and was handed a quote for $3700 including 6 manifold nuts at $7 each with the parts counter telling me these are needed when changing a cat out. These are just everyday flare nuts, nothing special and the stock ones are just as reusable as any other nut on a vehicle. At this point I started to consider using the $3-4,000 as a down-payment to trade in so I started browsing their site and see a $698 "documentation fee" tacked on to all auto sales, on top of tax and title. Can you imagine being so full of yourself you charge people a fine for choosing to do business with you?! In a state that banned junk fees these guys charge more than a month's truck payment LMAO. Anyway back to the cat. Looking around online I found the exact same OEM cat 45 mins away at Tasca Parts Online for $1,000 less. No other parts or hardware I didn't need added on. I did have to pay $440 shipping which they refunded when I picked up the new part at their store in Cranston. Yari over there was great to deal with and kept me informed on where the part was throughout the process. I paid to have it put on at a custom exhaust shop and its all fixed at last. While this experience made me a "one and done" GM owner it was great to work with someone that saved me so much. Words of advice when dealing with dealerships, especially ones like Mastria. -Always get a second opinion, especially when they start trying to sell you a credit card. Dealers didn't earn the "stealership" label accidentally. -Shop around. -Check consumer reports to see where the brand stands and why. GMC is #23 of the 26 auto brands for overall satisfaction. No domestic brands even made the top 7. GMC is only staying profitable due to "high margin" truck sales, a fancy way of saying "grossly overpriced". -Do your research on potential big ticket repairs, had I seen all the forums and enthusiast pages talking about this exact item I would have stayed with Toyota (#1 on Consumer Reports list)

Hi, my wife and I recently visited Mastria GMC in Raynham and purchased an awesome 2024 Acadia. We couldn't be happier with the experience and the purchase. I phoned Mastria GMC in the morning and spoke with Kimberly first to confirm the two SUV's we were interested in were still available. Kimberly confirmed they were available, and we made an appointment for 12 noon same day. We were greeted upon arrival by Sales Manager Josh Joseph. The dealership was busy, however Josh made a point to say hello and he'd would be with us shortly. We took test drives in several Acadia's and all were superb. My wife fell in love with the White AT4 so that was the one. Josh made the process so easy, no pressure and honored a price I had seen online as well as coming up on our trade in. Then, we met with sales Mike Dave who was equally friendly, personable, and knowledgeable and answered all of our questions. We came back on Monday to settle the financing with Jerry Chan who made the numbers work where we were comfortable. Again, Jerry answered all of our questions on warranties, coverage, and presented several coverages that we went over. Again, no pressure on the financing end. Overall, Alison and I were so impressed with the team at Mastria GMC, they made us feel welcome and really took great care of us during our visits. I would highly recommend Mastria in Raynham to family, friends and anyone in the market for new or pre-owned vehicle. Very good experience! Thank you, Rick and Alison

They are very helpful and professional. The staff listens and is responsive. I will definitely use them for our service needs.

I recently purchased my second truck from Mastria GMC in 10 years. The process was excellent. The sales people were great, very nice, informative, respectful and responsive. The entire process was outstanding from beginning to end and would highly recommend them. I’ve also been bringing my vehicles to them for all my service and that is also has been an excellent experience and will continue to use them for all my vehicle maintenance. Chris C.

I was very happy with the service dept. They were professional and accommodating. They made the necessary repairs and kept me informed about what was happening

Always a great experience at Mastria. I purchased an Escalade from Mastria Cadillac and continue to get my service performed at the dealership. The staff is friendly and accommodating, highly recommend!

I have purchased many vehicles through the years and my experience with Mastria is definately the most satisfying one ever. Shout out to Kerry Parkos and Meghan Shovelton for their professionalism and care. They were very helpful in making sure I left happy and satisfied. Thank you!

Kerry was awsome he finished the car one day Earlier the hole process went smoothly

Y best experience I ever had buying a car they made it so easy from the hm to the sales mgr the sales was very good and the Fiancé mgr was vey professional and easy to work with overall it was a great experience

Bought a vehicle, developed a power steering leak, 1 week after purchase. Dealership attempted to avoid paying for repair but, inevitably had to because it wouldn't pass inspection. 3 days later, call to get my car and I am told" best I can do is give you something comparable (which was a crap comparison vehicle) or your money back"?? For a new steering rack??? Oh, and a failed to mention frame issue, which I was told developed while parked on the lot, after taken in trade but, sold to me..🤔🤷 xxx!?! Long story short, FU Mastria!!! Took my money and business elsewhere, you will get no referral from me and, the owner of the company I work for, who does a great deal of commercial business with you, may be changing his opinion of your dealership. 😉👍

Excelent service they were very helpful and work was done well . The customer service was excellent we appreciate the service
