I'd never realised how similar the glasshouse was to that of a Karmann Ghia. I checked the Wikis which instructed me thusly: The man behind the project was an engineering consultant to Volvo, Helmer Petterson. Unknown to him, design work was done by his son Pelle, under the tutelage of Italian auto stylist Pietro Frua while Frua's studio was a subsidiary of the prestigious carrozzeriaGhia. ...which explains everything.
