Cars they make nowadays will rot out long before 50 years go by. They are DESIGNED to break down after so many years so that you will invest in a new one.
Sorry, but that is utter nonsense.
Modern engines, for example, will now last twice as long as their older ancestors. There are cheap brands that aren't made well but a typical MoPar V6, for example, might rack up 500 thousand miles or more with proper maintenance.
Americans don't want cars that last 50 years, they want a new car every three years because they're obsessed with keeping up with the Joneses but US cars can last eons if cared for.
Ever wonder why cab companies relied on Ford Crown Vics?
I keep hearing the same nonsense year in and year out.
This old girl is still running after 287 thousand miles.
It has NEVER had any major repairs done whatsoever.
The only reason it's being retired is because wifey wants something more luxurious and pretty.
