I'm always amazed at how well they can diagnose cars over the phone. They're entertaining to listen to and pretty darn knowledgeable.
They own a shop near MIT where they both went to school. I've always wondered how it would be to drop a car off to be fixed it there.
I live near there. It's nothing special. They are also cash only. Lots of times, they tell you to go to the Shell station down the street, which is actually not a bad place at all.
I have never brought my car there, but I know people who have. One said the people there are arrogant. Another said they are slow and are "not really that meticulous". I have another who said they are great. As with any other garage, it gets mixed reviews.
That said, come summer time, the place is always loaded.
