Donovan Brothers Automotive Services

Donovan Brothers Automotive Services is a family-run mechanic shop on Hancock Street in Quincy that BBB records list as 39 years in business, with Peter Donovan named as owner and Dave and Mo showing up repeatedly as the mechanics customers deal with. It carries a 4.9-star average across 91 Google ratings and an A+ BBB grade, though it isn't a BBB-accredited business. The last few months tell a consistent story. A cross-country road-tripper whose brakes started squealing as they neared Boston got a long, expensive repair list from a dealership, brought the car here for a second opinion, and found only a smaller fix was actually needed. Another driver had a dead battery replaced quickly at a reasonable price, and someone else got a burned-out headlight swapped in ten minutes for twenty dollars. The thread running through all of it is a straight answer instead of an upsell. That pattern isn't new. Reviews going back to 2015 describe the same honesty about which parts actually need replacing, and customers who kept driving in even after moving to Taunton, Bridgewater, or Medford. The consistency across years, and across Google, BBB, Nextdoor, and other directories, is what backs a rating this high rather than a handful of good reviews. One thing worth flagging before calling: everything here describes a general auto-repair shop — brakes, batteries, engine diagnostics, an occasional car air-conditioning recharge — not a contractor who installs or services home HVAC systems. Anyone looking for a house heating or cooling contractor should keep looking, but for a car that needs an honest second opinion, this shop has a long, well-corroborated record of giving one.
