Maybe Holden should have made this

Gemini had a windowless wagon to compete with Escort van, smaller load space though, and there was one called a Gemini 'Piper', dunno too much about it though.

It was called the Gemini 'Gypsy'. The Gemini 'Sandpiper' was a dressed up sedan or coupe (depending on which series).
