In his piece “Courageous Venture”, WB mentions “the rosy 1920s”, and proceeds to give some tax figures: £4 for a Tri-Car, £8 for an Austin Seven. Taking the average wage in the 1920s as £2 per week, this means two weeks’ wages for a trike, and four weeks’ wages for the Austin Seven.
I believe the average wage today is about £170 per week nationwide. This means the owner of a Reliant Robin would be paying £340 tax, and the owner of a Mini £680.
I think the only rosy things are WB’s spectacles.
