The Daytona, whose star-studded pedigree makes it irreplaceable, was in the shop for minor repairs after the Motorclassica exhibition in Melbourne.
It had been fully restored only three weeks ago.Those who have spent time behind its wheel include British Formula One legend James Hunt.
The car was owned by the wife of the owner of his first F1 team at the time.
The car was later owned by Roger Waters before business magnate Mohamed Al-Fayed bought it in the 1990s.
Al-Fayed gifted the car to son Dodi before he and Princess Diana were killed in a crash in Paris in 1997.
The current owner of the car, restaurant owner Enzo Ceravolo, bought the car in the UK five years ago.
