'Poverty Spec', I call it! Long been a practitioner of it. Even my latest 'wheels' is base spec, apart from upgraded satnav...... Mind you, base spec still included loads of stuff that would happily live without!
One reason I enjoy driving my 1972 Escort is that it has nothing unnecessary to get in the way of the experience. And yet the simple crude heater will scorch your extremities in half the time something modern would take!
