Ferrari 750 Monza chassis 0534 M, bodied by Scaglietti, was completed at the factory in early 1955 and delivered new to Count Bruno Sterzi of Milan. It subsequently passed through several Italian and Venezuelan owners, accumulating a documented competition history spanning Italy, Cuba, Venezuela, and Colombia before suffering a serious accident in 1961. Recovered from a Venezuelan scrapyard in 1976, the car eventually returned to Italy, underwent a comprehensive ground-up restoration, and received Ferrari Classiche certification, remaining eligible for prestigious historic tours and concours events worldwide.

Roy reviews and verifies every registration personally.

Each chassis record is compiled from public auction archives and links to its source material. Ownership, competition and maintenance entries are extracted from those catalogue listings by an LLM, which can make mistakes — please contact us with any corrections. The summary is Legacy Metrics’ own writing; we do not reproduce catalogue text.

“Full” and “partial” documentation labels indicate how well each entry is corroborated in the underlying sources, not an audit of the car’s physical paperwork. Names of recent or living owners are withheld for privacy.
