Callahan's Auto Service is a large garage located on a quiet stretch of Salem Street. Its friendly, helpful staff of mechanics specialize in wheel alignments, but will perform most kinds of general maintenance. Callahan's also features the latest computer scan tool equipment to diagnosis check engine light codes, an on-line program with the latest technical service bulletins and recalls and all the maintenance schedules for all makes and models. You can wait in their fairly comfortable office while your car goes under the wrench.
