Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

OSI built the spider on the Fiat 1100D chassis with a 1.2-litre engine and showed it at the 1963 Turin show. OSI was founded in 1960 by Luigi Segre of Ghia to build special series for makers such as Fiat and Innocenti.
