Guess who bought a C body Chrysler and shipped it from the US to The Netherlands last year
The normal-ish gas price is around 7.5USD/Gallon (which it is now) and the high was almost 9USD/Gallon.
Most older cars (40 Years and older) are converted to run bifuel, LPG and Petrol. (younger cars are heavily taxed)
LPG is only 2.5USD/Gallon around here.
When I was in the Army and stationed in Europe from the 1970's to 1990's we had a gas ration card. We paid the same low prices that we paid in the States.
