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

As a young child I was into Matchbox, Hot Wheels, Johnny Lightning, diecast cars. I then progressed into building plastic model car kits (spending my weekly allowance on a new one every Saturday (K-Mart)). Then around 10 years old my buddies and I built some go-karts using old lawn mowers (trash picking on "garbage night"). Then when I was old enough to drive it was just a part of my life. After I got married, and we started having kids, I sold my "toy car". When my youngest was about 6 years old, I found the Dart GT.
