I saw a really great documentary called Yank Tanks - it’s about the ingenuity of Cuban mechanics who often fabricate parts, turn chain saws in to mopeds, bake ceramic brakes in their back yards, all to keep 50+ year old cars running. “Every Cuban is a mechanic” is one of the quotes in the film- there were dozens of hacks and mods on the classic cars as well as the ways to repair them. The Yank Tank hackers are the curators of the largest, living, automobile museum in the world. Link.
