If you were a huge nerd in law school and are just itching for more personal jurisdiction hypotheticals, take a look at today's opinion from the Court of Appeal, where the issue is whether Audi AG -- which is the German parent -- can be sued in California for selling a defective Audi in California through its U.S.-based distributor.
Fortunately, you've got a "model answer" that goes both ways. The majority says that Audi AG can indeed be sued here, whereas the dissent says that, at least on this record, it can't.
So your answer is "right" either way. Depends on which professor grades your exam.
(Coincidentally enough, first-semester 1L grades just came out today at my school, so I'm definitely in an exam-pondering -- and exam-grading -- mode.)
