When did you start driving? Only getting 60k miles doesn't fit my experience driving japanese cars since the 90s. Our family had a 2000 subaru that clocked 350k miles before the engine finally blew up and we scrapped it. My uncle drives old volvos from the 80s since he can wonk on them in his own garage, and he gets numbers like that too. You look up user forums and you will find the same experiences with these decent old cars.

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.
