Also, the 1970s and 1980s were a low point for cars in general -- lots of new environmental regulations were kicking in (including a whale oil issue which was discussed on hacker news), causing objectively worse reliability for many cars in the 1970s and 1980s vs. the 1950s and 1960s. By the late 1990s the Japanese and German manufacturers seem to have resolved things, and by the 1990s, the US automakers.
