Why it matters
A luxury beach car on the Fiat 500 built by Boano at the request of Gianni Agnelli. Only two were built, and Carrozzeria Savio later bought the design rights and sold a limited run as the Fiat 500 Elegance.
How rare is it?
Six separate kinds of rarity – never combined into one number.
Each kind of rarity is rated separately and never combined.
02Production & history
Production
Every figure says what it counts.
| What is counted | Figure | Basis | Status |
|---|---|---|---|
| Total model productionOne of the two cars built is said to have been destroyed, leaving the surviving example | 11 | Surviving examples | Independently researched |
| Total model productionBoano Spiaggia beach cars made | 21,2 | Factory production | Independently researched |
Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
To make room for distinguished passengers on short trips, the chassis was lengthened. Two cars were built; one, owned by Aristotle Onassis, was later destroyed. A surviving car sold at RM Sotheby's in 2024 for EUR 370,625, according to the listing.
