Trouble free service of NANO

I am driving Tata Nano since 2011.My first car was base model. No doubt an excellent car I have traveled so many places like Digha, Puri,Chandipur, Simlipal Forest,Joshipur ,Tarapith etc several times,never face any problem. Fuel consumption approximate 21kmpl. With full load in hill area smooth running. Cabin is more specious than other small car. Second car I purchased in the year 2015, that is Tata Nano Twist XT ,it has everything like any luxury car. Fuel consumption is little bit more approx 19 kmpl with full Ac. Visibility from driver is far better than other cars. No doubt comfortable and trouble free performance. I like Tana Nano very much and request everyone to try once,I am satisfied with my car.
