As a mechanic in a fleet of over 100 vehicles that require a Mass inspection sticker, I can tell you that the services they provide is invaluable. On site vehicle assessments and inspections , no waiting, no travel,in shop, or on site. There team of professionals has minimized down time with there flexibility and willingness to work with us on schedules that we operate on day in and day out through out the New England region. By far one of the best phone numbers in our Rolodex, while the service is required but once a year. if you have them once you will never go back to driving to the inspection station...waiting in line...wasting man hours and fuel...
