There is no simple general answer to this.

Short-lived, fragile scrap has always been produced, and this has increased significantly.

Long-lasting, relatively robust engines are still produced today, even though there are not as many of them as there used to be and their maintenance effort/costs have increased significantly.

Define "more stable." More reliable? The old pre-chamber diesels without turbocharging from 40 years ago were more reliable and durable than any modern diesel, but what they lacked in power, they consumed more fuel.

Even the American engines from the time of the oil crisis had so little power from their displacement that they never broke down.

But the bread-and-butter engines of those days didn't last much longer than they do today and sometimes required significantly more maintenance.

I can still remember times when, at least for gasoline engines, 100,000 kilometers was considered quite a long mileage, and that after that, you couldn't expect much more. Modern engines seem to last considerably longer.

No. A petrol engine runs out of fuel at about 180,000 km, while a diesel engine lasts a good 100,000 km longer, both then and now.

Then you own the wrong brands.

All my Volvos have between 850 and 1.5 million km on them. All are petrol engines. And yes, they're still driven daily.

I'm not talking about Volvo or even old Mercedes engines. Those are qualities that are no longer offered today, and you're right about that. I've had Ford, Opel, Mazda, Renault, Nissan, and VW. All gasoline engines. So, "normal price, average quality." Mass-produced, in fact. One made it to 200,000 km. All the others broke down between 150,000 and 200,000 km. Even if the engine lasts longer, as the engine performance increases, you always have the problem of progressive wear and tear on the entire vehicle. At some point, the repairs become so frequent and so expensive that a used car is simply no longer worth it. And what's the point of an engine that lasts 1 million km if the owner is just going to buy a new car after 200,000 km anyway.

You're right, though. I personally buy cars new or used. I bought my last car in 1999. It was a Volvo.
