In 1962, I bought a Ford Poplar for GBP5. I was 17
I didn't have a driving licence, I can't remember if the car was taxed or insured!! And in any case I couldn't drive it either.
One day after my friend and another, together with three girls went for a spin on the recently opened M5
Not far, my friend lost control of it and the car turned over on its side and I remember vividly the sparks close to my ears - really scary. Minor injuries to all of us - cuts and bruises.
Not long before the motorway police arrived and names and addresses taken and later questioned - no further action for me as the owner but the driver was cautioned I think!
My first legit car was a second hand Ford van I bought in 1969 soon after getting married - then I was 24 and I learned to drive in that!
