There are many parts to cars. Don't forget the basic ones: exposed to the elements for decades, driven across uneven bumpy bits, even the 'consumable' parts also degrade fairly rapidly...
For an electric, I'm unsure on the long-term life of motors. Batteries are the main consumable, but are actually safer and simpler compared to hot oil and fuel separated by thin gaskets.
Still, even with the consumables exempted, I'm not sure that cars actually seeing road-salts in the winter and scorching sun in the summer last that long (40 years seems optimistic, and I know I HATE being behind any 'classic' ICE that no longer has to pass emissions).
