Back when the Savel site still existed, I printed all of the pages. I looked it up again. The car in question was referred to as the Savel Agora Série 2.
It was stated that Savel was founded by the Erad distributors in the six departments north of Paris and that Savel has taken over Erad. Further on there is no more mention of Erad, but only of Savel. The Savel brochures don't mention the Erad name at all, only the Spacia kept its "erad" moulding in the lower door panels. But that model was soon to be replaced by the Vigane.
