Tata designed a car named "Nano", keeping the lower middle class people of India in its mind.It is perhaps the cheapest car in the indian market.But a Nano can provide all basic facility as other cars as roof which saves from rain and sun, A/C which keeps you cool and most importantly it can accommodate 4-5 people.
Because of its low price built-up quality is bit low and it has 600cc engines which sometimes faces difficulty on hilly areas.But the fuel efficiency is also excellent as it is around 26kmpl.
I am happy with it.
