Hi,
There is a Ferrari Museum in Maranello, hometown of Ferrari cars. I am not sure about touring the plant alone but this can be organized for groups.
I think there is a company around Modena that could arrange that, but I forgot the name. Here is an example (I am not advertising it, I never ever worked with them, it is just the first result I got on Google)

Also, remember that you are entering the center of the supercar world ;-)
Near Maranello, you have Maserati in Modena, Lamborghini in Sant'Agata, Zonda in the area, De Tomaso was there too, and near Bologna you have Ducati for motorbike...

And then, the food is delicious in this area to top it all.

Have fun,
See you soon,
Thom.
