Anyone have an idea what average mpg in UK mpg a 525i touring 24v E34 auto will do to a gallon? Mixed, 25% town, 25% A road cross country and 50% 80 - 90mph motorway, brisk driving but not crazy driving. Also anyone know if there is much space under the boot floor to fit LPG tanks, do they have a full size spare wheel there? Cheers, Greg. ------------------------------
