Boxster is the roadster that sets the bar in its class. The same can not be said about other Porsches in the line up.
When I hear someone refer to the Boxster as a chick car I know two things immediately. One this person has little if any time behind the wheel in a high performance driving instruction setting and two the person is not too familiar with the brand.
Now that being said, roadsters in general get the "chick" car label. Despite the fact that nearly all, well the good ones at least, are fixtures at most track days and autocross events.
