For purchasing a new Tata Nano model you first have to book the car with a registered Tata Nano Dealer. However, the booking for year 2010 has already been closed by the company. You can book the car when Tata Motors will again start the bookings in the first quarter of year 2011. Thanks,
New Tata Nano with EasyShift is available at Rs. 2 lac (Ex-showroom, Delhi), and the final cost depends on the valuation of your car. So, first get the valuation of your car from authorized Tata dealer, so he can give you a final quote for the new car.
