I bought nano when it was new for UP. when I got it & use it approx 2000km. it gives me a bad experience. heating at the back bumper after a long distance travel. its size is small. its seat is uncomfortable . its engine sound noise after cover some distance. Leg room in this car is very small. we should adjust our self by bending our legs. its long drive was not comfortable for me. this car gives 20kmpl mileage on highway. its not a comfortable car. dealer satisfaction was good, he knows about it well.
