Michelotti and Triumph first discuss plans to design a fastback body for the Spitfire.
Production commences some three years later. By 1967, production reaches a steady 500-600 cars per month.
In autumn, the GT6 MkII is introduced. Chief among the modifications are a new, safer suspension set up.
MkIII’s flatter bonnet and chopped tail help to keep the four year-old GT6’s design looking fresh.
The last GT6s leave the factory, leaving its four-pot Spitfire sibling to soldier on until 1981.
