One-off Ferrari 166 MM/53, s/n 0262 M, with Abarth spider body was made in 1953 and originally delivered to Giulio Musitelli from Bergamo. Car was raced in Europe by Musitelli (during 1953-54) and in USA by several drivers since 1955 to 1960.
I'll try to post only verified information about Abarth spider and will be really grateful for any help from forums.autosport members.
