I think the reason Kaisers are so "invisible" is that you never see them in movies or popular culture. None in the "Cars" movies (to my knowledge), none in hollywood films. Hopefully that can be changed. Last week I signed my car up with a Nashville firm that supplies vintage cars for films produced in this area. What if the "Fabulous Hudson" in "Cars" had instead been a Kaiser, Frazer or Henry J? How many would recognize our cars then?
Even an appearance on a reality show like Pawn Stars, American Pickers, American Restoration, etc could help visibility.
