Can someone just for once state, What is the Fuel Consumption of a 1.3L Liana & a 1.6L Liana; so that we can have a fair analysis of the Consumption/Power of the cars in question.
if iDSI gives you 1 or 2km/ltr more; And Liana's M13A pushes more ponnies and Offers you more for a less money, then regardless of how much iDSI is advanced or a Marvell, its useless!
This is just the same situation as You keep a bird in a steel cage or keep it in a cage coated with gold!
In both cases the bird isn't free! albeit the Gold one costs you more, it offers you nothing but eye-candy!
L12A2 might be the Gold Cage and M13A might be the steel one; that is Until the real Facts and on-field un-biased values are presented.
