"To get an idea of the impact that the RS had at the time, it must be emphasized that the first 500 to be produced for homologation will be sold out, even before the Paris Motor Show opening. The remaining 500 will also serve to accreditation, but in Group 3. As the story goes,it’s sad that in only the first day of the opening of the Paris Motor Show, will have been sold 51 RS units."

Only 500 for Group 4 Homologation. Although actually a few more were done before they received approval.
