In January this year, Ratan Tata fulfilled his promise by launching the cheapest car in the world at an auto expo event in India. The car, called Nano will be costing a mere $2500. Though the car will be officially released only in the latter part of this year, it has already created a lot of hype among the people of this country. Everyone is happy with the launch of the car and would like to buy one, once Nano is out. With already a billion plus population, of which a lot of people are from the middle class, Nano is set to change the way, Indians travel.
