Chassis #0887-508 — Base Fiat 850
This S1 is documented primarily through its original Italian registration document (libretto), which provides valuable historical information. The handwritten document confirms the Fiat 850 base, the Moretti body designation, and the original registration details.
The registration paper shows the car was first registered in Italy and documents key technical specifications as recorded by the Italian authorities at the time of homologation. Such original paperwork is exceptionally rare for these cars and provides invaluable evidence for establishing production dates and specifications. This kind of documentation helps researchers piece together the production history of the entire Sportiva range.
