When I was 14 my dad bought a '69 Bronco and we completely stripped it down to bare metal, painted it in our single carport with laquer and then reassembled it.
The instant I got my learner's permit, he taught me how to drive in it - 3 spd on the column, manual brakes & steering. After I got my license, we shared it.
Then I bought my first car, '70 Torino GT. Naturally it didn't have an engine or transmission, so I continued to drive the Bronco!
