Your Earliest Fast Car Experiences?

I was eleven, maybe twelve and my parents were avid scuba divers
It seemed each weekend they would be out on a dive, somewhere
They were part of a club and there were usually 2 or 3 dozen other people diving with them

This one particular dive was at the Bodensee in Germany and my parents let me ride back with another diver they knew
A blond girl in her mid 20s driving a champagne colored 911 Porsche
I think the moment that car his the autobahn I hit puberty
