A very nice website I came across recently. This guy has been doing an excellent and impressive job in tracking all Dutch registered Ferrari's (and Lamborghini's).
http://www.ferrariregistry.nl/ or http://www.ferrari-register.nl/
My car was only spotted once outside on the parking place at the Kroymans showroom.
Again a nice contribution on my car history.
From this register I make up we have about 107 times 365/400/412 in the Netherlands. Likely a bit more which are stored and hide away.
