Ah, close but not quite.
The original Tiger Woman is my sister. Her oriental zodiac sign is the Tiger, and there is a long story about why she is called Tiger Woman that has to do with a business trip her husband took to Japan many years ago.
Tiger Woman #2 is my sisters boat here in California. Men always seem to name their boats after their wives, and since their sailboat already wears her real name, her husband named the power boat Tiger Woman in her honor.
And the 3rd Tiger Woman is indeed the car that Julie was following. (Sis is big into naming things..)
