Right now the car industry is moving toward the Tesla model of molding much of the car as a single piece of material. This lowers the cost of manufacture (fewer parts), but if any part of the car gets damaged then there is the possibility that the car will be unrepairable if the damage is significant, rather than just replacing the panel that was damaged.
Back in the mid 80s, an aunt’s then husband was a higher up engineer and he told a few of us at some gathering that his roommate got a job at GM after graduation.
His first job was to design parts to wear out in 6 years.
I really like the Ineos Grenadier (a newish truck, very old school) for that reason.
Every bit of it is modular and easily repaired in the field.
