> Cars that live 20+ years are probably a minority. That seems vastly unlikely? But I don't have stats one way or the other. My newest car is 19 years old and it's like new for all purposes. My other cars currently are 30 and 35 years old and aside from paint faiding they are as good as new. With reasonable maintenance, cars will last for many many decades.
You are by far the exception, especially since being on HN, you're most likely to be middle class or higher. Poor people have cars that old, usually, there's a reason they're called "beaters". People in general try not to have cars older than around 7 years if they can, that's the "public wisdom" regarding when cars start having bigger maintenance problems.

And GM (and ...) probably see that as a "revenue opportunity".
