I brought my 2024 GLC 300 in for a safety recall service.
I brought my 2024 GLC 300 in for a safety recall service. Matt Santiago the service advisor was pleasant and efficient. He said it would take 1.5 hours and it was completed right on time. Also, my salesman Rob Cappeletti stop by to see how I liked the car and if I needed anything. The new facility is very impressive.

Trouble on the Cape
Viti exceeded our expectations. Their service department went above and beyond any experience I’ve ever had with any dealership! Our convertible top was stuck in the open position on Cape Cod. The service manager Tony picked up the phone at 7:30 am on Monday, my car was in the shop Tuesday morning. Russell, our service rep, called Tuesday afternoon car was ready for pickup Thursday. To top off my experience they delivered the car back to the Cape Cod!!!!! The absolute best experience of my life with a dealership!!!
