Production cars with no known surviving examples

There were loads of short-lived car manufacturers early on. I remember when old-timers would talk about how there were a half-dozen car companies in Anderson, Indiana. Rider-Lewis, Lambert friction-drive, Nyeberg, and Madison (most of the factory building is still there in disrepair) are four I could Google up quickly. The odds there being any surviving examples are quite slim.

A friends’s father drove a Pontiac LeMans, probably about a 1990 model year. Even back then, they were uncommon and I haven’t seen one in decades. Looks like they were Daewoo imports.
