The car is best for mileage as it's a CNG version but it's horrible for long drives after around 100km driven when the engine gets heated it totally lacks in pickup, bad suspension, waste plastic quality, if your priority is only mileage then go for it otherwise don't think of it. It has very poor build quality too,
some people might be not agreeing to this but it's my personal experience don't waste your hard-earned money on this car there are options like grand i10 nios Magna, & even Tiago which has all the thing which anyone wants from the entry-level hatchback. believe me, you will get bored from this car within a year. get a car which has a 1.2 ltr option.
