How we work
Find the cause, not just the symptom.
Every job starts with the question of what is actually wrong. A warning light, a noise, a car that will not start: we look before we replace, and we explain what we found in plain words before you decide anything. The four things Massachusetts rules for repair shops cover, and how they work here, are on the home page under How a repair works here.
