When did you "know" you were a car guy?

We lived in Dawson Ga. and parents bought a somewhat used 55 Pontiac. Dad was the parts man at the local little town dealership. I was 9, and it was 1957, and they went from SW Ga to somewhere in Fl to pick it up. Mom drove it back with me, I remember her saying " Lets open her up and see what she can do!" Probably about 110 or so. I was like lets go faster mom!!
I learned to steer in it, sitting on her lay bout age 10.
First fast car I had a ride in was a 62 Impala 4 speed 409 I was maybe 14. He pinned me and is cousin back hard in the seats! laughing his *** off! I was like WOW!!!!!
