When I first passed my test, my oldies let me drive their Ford Anglia 100E. What was wrong with it? A few things spring to mind:
It was made in about 1959, and had a side valve engine and 3 speed box. No manufacturer outside the Soviet Union (other than Ford) still made side valve engines. It drank petrol and oil, and had so little grunt, I had to change down to drive into a head wind.
The windscreen wipers worked by drawing a vacuum from the inlet manifold. They ran at lightning speed downhill on over-run, and stopped when I put my foot down.
The worm and recirculating ball steering had so much slop in it (no, it wasn't worn out) that my arms used to get tired from juggling with the steering wheel, and I looked forward to long, sweeping bends so that I could hold the wheel in one position and have a bit of a rest.
The brakes were on or off. There was no such thing as gentle application of them.
The handbrake needed both hands or the co-operation of your passenger to set or release it.
