nice to see some fellow countrymen in here. those bantams are nice and light! you should maybe just pump the front tyres to max there is not alot of weight on the back so you wont loose out too much running them at a lower pressure. i would browse gumtree to try find a tonneau cover. apparently that helps a lot! My granddad has this car and he always complains about the poor economy he averages 9L / 100km all be it with a big boxy canopy so you are doing pretty good.
