I’m a natural for mending cars ( not ) but then these days, no one opening the bonnet of a car will recognise anything. This is a drawing from some years ago when I celebrated the work of 1930s cartoonist Pont who celebrated the way the British behaved. Please note the arriving cup of tea from a support worker. Unusually there are no oily kids around here, they’ve probably run off with an oily part that is vital.
Paul Davies Cartoons & stuff 
I remember the feelings well, although the tea would usually be a most welcome break in the frustration.
Thanks for all the fond memories and hints, I still have a 1935 Morris 8 sitting on blocks in my garage, crying out for some little “fixes”
