You can see below what the Rotaver Swissmobil should have looked like when the project started in 1987, which really would have been a completely Swiss-built car. But a year later an article about the Tour de Sol just says "Rotaver aus Lützelflüh baut an einem
französischen Kleinwagen" (Rotaver of Lützelflüh is working on a French microcar) which obviously is the puzzle car based on a Ligier Série 7 JS 12.
