bro that average is taken on ideal conditions which is difficult to attain,you asked me how i read that this is fuel average column,read on top of last column it is written km/lit ,that is fuel average nothing else,i asked my friend who is in japan doing his Phd to check from toyota japan motors about fuel average of these versions,they told him that on ideal conditions and in busy traffic 1300cc gives more mileage.ideal condition is 80km/hr with no breaks applied and it includes tyre pressure ,fuel quality and many other small variant factors. Now coming to resale of these vehicles in pakistan,if we sell F extra package and 1300cc after 5 yrs of use,you wont get the same amount difference which is there when we bought it,we can see this from GLI and XLI resale difference graph,coz here in pakistan ppl say that they can get power windows and seats changed by spending few extra bucks then y to pay this much price difference,though they dont prefer factory fitted originality,this is mentality of pakistani ppl car market
