I brought one and it seems to me driving the same through city like a piece of cake. Great manuerablity and steering push back other vehicles in the same segment. I would say rather buy a nano than going for an 800 or an alto.
Check this too. They have made the test drive removing from minds all my speculations regarding the perfomance of this tiny little car. https://youtube.com/watch?v=3sZitve3SUw
Hats off Mr.Ratan Tata. But the after service expectation from the showroom is not much good that expected. Insist them to give same priority to the customers who have nano and other midsegment cars.
