Developed in 1999 and introduced to the marketplace in 2000, Muscle Machines was formed as a division of Funline Merchandising Company. In September 2003, Funline was acquired by what is now Motorsports Authentics.
Series One comprised of 16 different paint schemes and a chase car. A five pack offering will also be available and cars will include classic rides from the 1930s through the 1950s and muscle cars from 1964-1972. Additional Muscle Machines product offerings are in the works for 2008.
