Seventy Years and Counting

Mastroianni Auto Sales and Service was started by John Mastroianni Sr. back in 1945. The business began on Liberty Street in Springfield MA with two service pumps and a two bay garage. Jack Mastroianni worked for his father as a boy and then in 1964 began his own used car business on his father's lot. After 60 years of doing business in the Hungry Hill section of Springfield MA, Jack moved Mastroianni Sales and Service from Liberty Street to Thorndike Street in Palmer MA in 2005.
