Ah, the good old days
Let's throw in a little perspective. Cars used to run without proactive renewal, but then they used to be shot at 60-70K miles and not worth it to repair. And it felt like you were driving an old car.
Now my car has 96K miles and I'm replacing parts because it still feels and looks like a new car. I strive to make it feel like the day I picked it up new with all the tolerances tight and the handling and acceleration still solid.
So that water pump that you never replaced before was part of a car that never had a great shot at going over 100K. The car around it collapsed before that time.
