53 Chevy - my dad used to let me stand on the seat and steer when I was about 2 1/2. Then one day I decided to fly solo. I watched how to release the parking brake (turn and push) and down the driveway I went. I finally ran out of grade without hitting anything. Beginner's luck perhaps.... My first drive with the motor on was a 57 Plymouth that a cousin let me drive in a large field when I was 11. Great donuts!
