I was 5 or 6. I would pull the Pontiac Tempest out of the garage for my mom. When my parents weren't around I would go up and down the street. Wrecked my uncle's car playing in it with my cousin showing off my new skills with motor not running. (Making car sounds). Put it in neutral and car started rolling backwards. We bailed and watch it go down the driveway across the street and into the ditch. Amazingly I didn't get a beating.
