I started in the 80s and my first few cars were from 70s or early 80s. Back then most engines lasted around 100000km and cars rusted pretty badly after 10 years. That has improved enormously since then. Engine management has also become more reliable. Carburetors needed constant maintenance once they got older, so did the ignition systems back then.
