Why it matters

The Boomerang is Giorgetto Giugiaro's sharply angular Italdesign concept built on Maserati Bora mechanicals. Bonhams calls it one of the most remarkable designs of the 20th century and a forerunner of the wedge style later seen on the Volkswagen Golf Mk 1.

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

History

The car was first unveiled at the 1971 Turin Motor Show and returned to the 1972 Geneva show as a fully operational vehicle on Bora chassis 081. It has since appeared at Villa d'Este and Pebble Beach and remains road registered and in working order. Bonhams offered it as lot 11 at its Chantilly sale on 5 September 2015.
