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

I had Hot Wheels, slot cars as a kid. Got into racing BMX in the early 80's. Rode to model train shows in the 69 Charger I now own.

Bored as a 15yr old in rural MD with a cornfields outside my window - hot wired my parents 'backup" car - a '66 Cadillac Calais, key on the dash, three wires. Rode around in the summer when they were at work. I was a bad kid.
