The team at Mass Diesel are top notch! They are the only shop I bring my personal and professional equipment to. Totally transparent service and good turn around time. 10/10 would recommend.

Great place. They did the job even though it took them longer from no fault of their own and they did it honest. Found out the part they put on was not the problem and didn’t charge us for the labor they used to get to the diagnosis. Will be back.
