I said "correct" about what you wrote. I can't say that driving on LPG doesn't cost me anything, converting the Zafira to LPG cost me the modest sum of 3000 €. It is a desire to use a cleaner fuel that led me to this change and not its price per liter is a second argument that works in favor, that's all.
PS: choice between gas and diesel: quickly because gas burns much more cleanly than diesel in an automobile.
