My '70s vehicles were pretty good, actually. I was still driving the 1975 Bus my parents purchased used in 1981 up into the '90s. Its Bosch L-jet EFI system insured it ALWAYS started.... hot cold, bitter cold, didn't matter. The odometer was rolled twice, and almost a third time, before rust just got the best of it. But it never once broke down. I still have the '79. I think there were some pretty abysmal cars during that time, but most were American.
