>They have no ECU to brick, no adblue sensors to fail and put the car into limp mode

Which means they are some of the most polluting and wasteful cars available. ECUs are good. They make cars safer, more reliable and more efficient. Car manufacturers had to be dragged kicking and screaming to add adblue, because the Diesel engines are pretty toxic otherwise.

The apologia for old cars is just insane, they are not what you think they are.

>If your C15 breaks down in a field, you can fix it with a wrench.

This is just delusional.
