> I can guarantee if someone sold unrepairable cars then there would be a revolt. This is no different.
You do realise that to build a car from its parts catalogue would cost many times its list price? The cost of replacement car parts - often hidden from us directly because of insurance companies - subsidises the cost of new cars. It's been that way for decades.
This revolt of which you speak - I've seen no sign of it in response to easily damaged and expensive colour-matched bumpers fitted to almost all new cars.
