Lightweight, then powerful, cheap & rugged Model T changed the world on car for the masses instead of the elites.
It had long run with lot of innovations. However, things changed. Better roads, competition caught up, & drivers wanted bigger faster covered car. Let say drivers forced to bundle up in the winter & later covered metal version weighed more.
Nice short book. Chuckled on hot rodders vs keep as way it is car collectors factions.
