I bought Tata Nano CX Model in April 2010. My experience is amazing with my Nano. Inner space is as bjg as tall and hefty person like me can easily seat and drive the vehicle for hours. Average of the vehicle is also very good. It’s around 22 km/Per litre on highways with A.C and 20 Km/Litre in City.
One myth is there for Tata Nano that, it’s a city car, but in my view it’s also comfortable on highways, last month I drove it to my native place Rajkot which is almost 460 km away from Surat. I accelerate on and average 80 - 90 Km/Hours without any problem. Long journey is also comfortable in this car.
If we think about some negative points than worst is no luggage space in side but still it’s a good car A.C is also powerful.
