I would like to see a comparison of petrol prices as paid by
motorists, over the years since the end of World War 2 (in UK)

The AA Motoring Trust has published figures going back to 1896, and I
was interested to find that a gallon of petrol cost less than a
shilling until 1906.
By 1945 it had gone up to two shillings! (Ten new pence) 
http://www.aanewsroom.com/aamotoringtrust/pdf/petrol_prices.pdf

Government figures going back to 1970 are available in Excel format.
"Table 4.1.3: Typical annual retail prices of petroleum products 1970 to 2001"
http://www.dti.gov.uk/energy/inform/energy_prices/tables.shtml

Please ask for further help if you have difficulty with these links,
or if you would like any clarification.

Best wishes - Leli
