In 1958 petrol was the equivalent of 5 p /litre.A Police Constables salary was £510/year.
In todays terms that equates to qabout £2.50/ litre .Hard to believe that petrol is only half the cost now as then. Makes it seem a bargain really
The source of my research was a birthday card in Tescos that gives the cost of things on the date people were born so I cant vouch for its accuracy If I were an MP I could claim thousands in expenses for that bit of research.
