Well, again, just what do you mean here?  Does Ford manufacture the class of
Mustangs?  Does Ford manufacture some Mustangs?  Does Ford manufacture all
Mustangs?  Does Ford necessarily manufacture all Mustangs?

What you probably want to say is something like

Class(Manufacturer partial)
Individual(Ford type(Manufacturer))

ObjectProperty(manufactured-by Functional)

Class(Car partial)

Class(Mustang partial Car restriction(manufactured-by someValuesFrom(Ford)))
