- Colour
- Traditional racing red ('Rosso Corsa')

Chassis 0058 M is the 23rd of 25 Touring-bodied Ferrari 166 MM barchettas produced, completed in June 1950 and delivered initially to a Genoese company before passing as a gift to rising Italian racing driver Eugenio Castellotti, who campaigned it extensively in 1951–1953 across Italy and Portugal. Exported to California in late 1953, it competed in early West Coast road races before entering a long period of concours prominence, notably taking the Hans Tanner Trophy at Pebble Beach in 1979. The car retains a high degree of originality and carries documented period racing history alongside a celebrated show career spanning several decades.
