History
Car was assembled at AMI, Port Melbourne. It was originally to seek public opinion whether it could be sold beside the GT 6.
I was employed at AMI and watched the hand assembly of the car and fell in love with it. Due to BL taking over the Triumph build, it never was shown to the public.
I believe there is another GT4 in England, owned by an ex Leyland engineer.
