You are right and this is what i am saying here from 1st day since i bought it.
Similar thing can be applicable to new corolla you get it in 17-18 lacs, now you can get Axio, allion, premio and many other good JDM cars in this price, So why making fuss for only Wagon R. Resale of car will take time specially it is completely new car not a new model of already popular car. 3 years from now, Wagon R Vxl will be selling at around 10-11. Nowadays everything is getting cheaper due to petrol prices and stable PKR against top currencies.
