Well first when tata nano was launched their were some scary incidences which droped down their sales, but now 2015 gen x proved everyobe wrong and it is one of the best baby car for those who has small family.
Their is no much difference between the past generation nano and gen x 2015 but the simlie simlie grill bellow the headlights makes it awsome to look at and tail lamps are also good enough to look at. The interior of the car is decent but its not that comfortable to have long drives, in poor condition like ditches/holes on roods bumps the car. This car is not as smooth as in poor roods. It gives you aroung 20km to 25km per litre. overall its a great car to ride.
