With enough time and skill sets, could a modern car be modded enough to work without microprocessors?
Having machining skills and a fitted workshop, without buying a new motor block or transmission. Through modding of its parts or machining new ones. Discrete electronics could be used (to build multibrivators and control some logic or power output stages) but no microprocessors or very integrated systems.
Lets say an EMP destroyed all microelectronics in a community and people have already depleted the stock and spare parts of old cars.
