I found these pictures with the following discription.
Varela junto al Andino GT. Detalles del interior
and the third pictures sais.
Varela y sus colaboradores, junto al Andino GT el día de la presentación en el Autódromo de 9 de Julio en agosto de 1968 (Foto por gentileza de Luis Varela)
Both pictures are from articles with full discription of this car, the history and its designer.
No mentioning other then Andino GT though, or is it Andino GTA (Gran Tursimo Argentino)??
