i dont think it will take off tbh, simply becuase there arent enough filling stations out there who sell it, also look at the lpg cars and hybrids etc, ive not seen one station near me that sells it or within a 30 mile radius, they would have to market it in such a way that it would have to perform better than petrol and be cheaper and more economical than diesel, also this country would never offer you a cheap alternative the robbing b*****d goverment
