VW of Old Saybrook is a dealer and service center on the "Auto Strip" in Old Saybrook Route 153. My experience is only with the service/parts department.
They do offer "loaner cars", if you book an appointment about a month in advance. Other than that, they offer a free shuttle service to get you to/from local areas, while your car is being serviced.
The mechanics seem very knowledgeable and efficient. The work is done when they say it will be done, and they always provide a pre-estimate before beginning work. However, their professionalism (especially of the administrative/desk staff) leads something to be desired. I have been left on hold for 15 minutes, been asked to "call back" rather than have a mechanic return my call, and have waited at the counter to pick up my car while the staff chit-chats with their back to me. And while I do appreciate their customer surveys, they are a little too aggressive, calling multiple times and sending a written survey
