But then a modern fiberglass car is more complex than a 60s steel truck. The latter eats more gas, but if they two get in an accident the truck is all that's left and those practically illiterate can readily fix the components of it as needed, no dealer specific gadgets and lock-in, you can even bore out new holes mounting in different engines if they can move the steel on wheels.

It is more complex, but mostly for reasons that serve someone else than me.
