There is much debate about what size fox would cave-in the front of an A40 and not leave any blood or guts in the radiator. My brother sticks to the story and mum believed it............. perhaps.
It did mean that she bought a fiat 850 sport which my brother had great fun in.
Mum thought it was quite fast too but she was looking at the rev counter and always kept to 3,000 revs in a thirty! We tended to avoid lifts in the Fiat with Mum driving!
