This site: https://en.wikipedia.org/wiki/Car_crusher says the first car crusher ('pancake machine') was developed in 1965. It goes on to say further development led to machines that could fold an entire car into a cube, but doesn't give a date, though obviously it post dated the development of the simple 'pancake' presses.
