I have been going to Shawsheen Sunoco for over twenty years for service. I do most of my auto maintenance myself, but when I am in need of a repair I can't handle I go to Shawsheen Sunoco. I have had Electronics diagnostics and repairs, chassis, exhaust and wheel alignments, tire mounting and balancing done here with fair pricing and professional service every single time. There is also a warranty with the repairs. They have done repairs on all of my family's cars also without a complaint. They are always careful with my cars.
