I own this model and very happy to share my feedback. Nano is not just a city car, it is much better than any other hatch back cars, I have driven Tata Nano from Virar to Karwar, Shirdi, Akalkot, Gangapur, Kolhapur and Pandharpur.
The car is very much comforfortable for 4 passangers, since it has power steering handling the car is effortless.
When you are on long drive music plays important part, and Nano has inbuild music system, even the longest person can sit and drive the car comfortably. Being a small car need very less to get into any road mostly in village areas. NANO is one of the biggest achivement from Tata so I recommend people to experience this car which gives a economy drive and is always light on your pockets.
