Not sure which car you've been using but cars have been getting quite reliable.

I have a 2001 BMW 330i that's on around 363k miles (~580,000km) and still running the original factory drivetrain. The only parts replaced so far are wear parts in suspension and brakes (common with EVs) and some coolant pipes (probably also needed in EVs).

????? At 175 000 km, you're barely getting into the "old" territory. I've driven cars that had 350k and were still doing fine. The only major replacement you should have had by then is changing the timing belt. And even then, some cars have a timing chain that just straight up doesn't break.
