There is a good one in Bellingham Mass, which is about 45 minutes from the heart of Boston.
Mass Pike to the 495 South, get off at exit 18
Marty's Auto Service
46 N Main Street, Bellingham, MA
They fixed my SRT8 after it had over $6k of Hail damage
Then 3 weeks later, my wife crushed the quarter panel with her Dyrango & they did a great job fixing that as well.
They guarantee their work.
