Ease of repair has largely been replaced by lack of need of repair. Cars, especially IC engines, are so much more reliable today that repair is relatively rare. Engine rebuilds are almost unheard of on small cars. Transmissions regularly outlast the chasis. Even tires rarely get flats. People now expect to drive many tens or even a hundred thousand miles without engine failure, on no more maintenance than an occasional oil change.

Ease of repair is a factor, but there are other factors. Safety and Fuel Economy (Aerodynamics and mass) are more important than ease of repair so many things to make it easy to repair just get tossed out.
