The other way of getting into the Ferrai factory is to sell them something! I am scheduled to be in the factory in a couple of weeks. They are buying some of my company's software and I will make a special trip to 'supervise' the install.

Ferrai does do factory tours to busines partners, but it is not all that interesting as most parts of the factory are offlimit. I have never seen an italian company, including banks, that are as secretive as Ferrari. These people take security very seriously.
