If you bought a used BMW or Volvo in the 90s with 150k km on it, you would definitely have a reasonable expectation that it would last another 7-8 years. The people I've known with extreme mileage have been like 400k or 500k km.
The manufacturing quality lessons of Honda and Toyota started to hit US in the 90s. I toured a Ford engineering division around then, where they just starting to adopt ideas like empowered workers and continuous measurable improvement. Anyone could stop the line if they saw a problem.
With service schedules, free warranties, and checkups... that's probably not a problem anymore in the USA. So it could be a change in culture that is allowing people to drive further these days. A lot of cars these days come with 3-years of free service at the dealership, allowing for oil changes (and other maintenance items) to be checked on regularly.
I dunno how it works in other countries, but my understanding is that it wasn't always like this in the USA. So buying used cars with bad maintenance problems was more common back in the 90s. In contrast, you can often get the service history of the used cars you buy today (if you're buying certified used, for example).

So I don't really know why cars are lasting much longer these days. But I definitely know that back in the day, 100k miles was a thing worth bragging about.
I've mostly heard horror stories from my dad about how some of his neighbors didn't know how to take care of their cars.
> In fact back then car owners probably had more awareness of how oil changes worked since tasks such as oil changes, spark plug replacement, tune ups, brake drum/pad replacement were much more commonly done by the car owner than they are today.
On that point, I think I can agree, at least based on the stories I've heard of that time. But the question is: what about all the car owners who didn't know how to do those things? The car owners who weren't in the know?
It wasn't like today where you could easily look this stuff up, you had to have been brought up correctly in the correct car culture to know those sorts of facts.
Only when cars broke down, they would come around to the "car guy" in the neighborhood to ask for help. And that's when you hear the crazy stories about how many people didn't know how to handle their cars.
Knowing that your car needed regular servicing wasn't some secret fact that you had to somehow search out or be raised in the proper household to know. Like today it was common knowledge and service information as such oil type and frequency of service was included in owners manuals just as it is today.
Did some people then not take care of their cars? Yes, but it is the same today.
As for how you learned to fix or service a car yourself if you weren't raised in the "correct car culture", you went to the library and looked it up in the Chilton repair manual for your vehicle. Most libraries had some physically and a more complete collection on microfilm from which you could print out the pages you needed.
I was in middle school and high school during the 80s. In this time it was common for middle school/junior high students to be required to take industrial arts along with home economics. Industrial arts included things like wood and metal working, printing and in many school districts small engine repair. In my school district during part of 7th grade all students tore down and rebuild a 4 stroke lawn mower engine.
Increasingly many manufacturers apparently don’t really care about the final on the road price staying as low as possible all that much within reason; it’s more about how expensive a car can we push on people at lease rates their wallet will stretch to. The “you can drive this for just $xxx a month!” is the conversation the dealer typically focuses on, probably to obfuscate the true cost as much as anything else. This admittedly applies more to say luxury European brands, where many model lines have (adjusting for inflation) gotten more luxurious and expensive as the focus has primarily shifted to leasing in many markets. There’s similar issues with the truck market as well, and America still buys lots of these every year.
IMO, what explains the higher price is because reliability is so much better than 20 years ago. 100k miles is so cake that no one brags about reaching 100k miles anymore. In fact, most people today are bragging about "oil-change + tire maintenance only for 100k miles".
Its completely reasonable to buy a car with 100k miles on it, and hope for it to last another 100k miles on top of it (or ~7 years or so, depending on driving habits).
In effect, a 5-year old car today is approximately worth the same a brand-new car from the 90s. You're gonna get +100k miles off of it and not have to worry too much about maintenance issues.
