Over course, I doubted him, but he went into great detail about how he had to drive in post-war Germany, as they couldn't afford replacing anything back then, so everything had to last. He was extremely careful with his down shifting, and only barely touched the breaks at the very end. Accelerated very slowly, etc...
I wonder how much WWII played in Germans making solid stuff still to this day. (and the rest of Europe)

His point is that what you have is a nice anecdote, and survivor bias means that you only hear about the products that ended up lasting, but not all the Mercedeses that bit the dust along the way.
And now that everyone makes dependable cars, they simply change the headlight/taillight configuration every year to make one's car seem out-of-date much sooner.
Those infotainment centers don't help at all, either.

One example of this: the exaggerated "tail fins"[0] that characterized late-1950s American sedans started small, then grew almost annually for a decade.
MAD magazine had a great feature in the 1970s called "Planned Obsolescence in Everyday Products", parodying design fails in household appliances and such.
