Reaching "Classic Ferrari Shutdown" (CFS) in the "Master" series is a major milestone in the game, because it will open to you farming for good volumes of R$ and fame/.

The path there is

1. Reach level 30 OR finalize "Aston Martin Expedition" in "Expert" unlocking "Open Sky Challenge" (OSC)

2. Finalize OSC unlocking "Euro supercar duel" (ESD)

3. Finalize ESD unlocking "Red line origins" (RLO)

4. Finalizing RLO unlocking CFS

One of the major problems you will encounter is the 3,6 Mio $ for the Ferrari 375 F1 in RLO. This is a pain in the beginning of the game.

I reached CFS @ level 50 using this path.

Getting any of the cars involved during a sale is one of the fastest shortcuts because it will automatically unlock the series involved; to my knowledge none of the ferraris in CFS have been offered until now, but some of the others have.
