1960 - 12 years old, I bought a Morris Z trayback ute for 5 pounds (in Calamvale). I picked strawberries for months to raise that - I received 6d per one-gallon tin (5 cents/5 litres).
It cost me another fiver for the battery.
Imagine this as a wooden traybacked ute:

My next car, at 15, was a Renault 4CV.

When I was 16 I bought a 1938 Vauxhall Model J 14hp and drove it unlicenced and unregistered from Brisbane to Sydney (in 1964). :)
