I just checked and Maranello is 291km (3hr 21m) from where we are staying via the A1, so this may take a bit of planning
As an aside, my manager owns an old Lancia and beleives he could get us into the factory/mueum for a visit, which is by apponitment only:
Collezione Vincenzo Lancia
Via Caraglio 84, Torino
Ph: +39 011 00 321 00
Open: by appointment
Belongs to the Lancia Club.
This is 179km (2hr 30m) from where we are staying. It also happens to be 5.8km from here:
Museo dell'Automobile. Carlo Biscaretti di Ruffia Turin
Corso Unita d'Italia 40, Torino

This place has some great reviews on other sites.
Don't want to turn the trip into a museum run but thought it might be worth mentioning as an option.
