I should say "We did it" because, this time, I am teaming up with a friend who has owned, restored and maintained numerous vintage Italian cars.
About a month ago we spotted a '62 FIAT 1500S 'OSCA' cabriolet in very poor but restorable and complete condition for sale on Los Angeles Craigslist, in Long Beach, being offered by a longtime collector of FIAT and Simca cars.
It needs extensive rust repairs, which I will take care of, and has the original OSCA (Officine Specializzate Costruzione Automobili—Fratelli Maserati S.p.A) engine, that has already been rebuilt. OSCA was an Italian manufacturer of racing and sports cars established 1947 in San Lazzaro di Savena, Bologna, by the Maserati brothers, and closed down in 1967.
