No idea, but if you are trying to get the attention of someone high up
in the food chain, there's a better way. Hunt down where the person's
office is, FEDX them a letter. Mark it "personal and confidential".
That way it gets read by their Admin since no one will dare open it...
and it should get sent to someone senior in management once read. well
worth the $20 for FEDX.

That is assuming anyone at Nissan cares at all anymore what customers
think - I don't much hope :-(
