The Maco was created by John Silva in 1969 after realizing that the new (1968) Corvette body style didn't look close enough to the 1965 Mako Shark II show car. John made 125 of these cars from 1969 until 1979. John Silva made 3 Maco's for Motion Performance and then Motion Performance took a mold off of one of the cars and began selling the Maco as a kit as well.
Over the years there have been a number of people that made molds of these cars and who have sold their own version.
