After so many user review and auto expert review n video, I have finally choose TATA Nano .as its really an budget car, giving good seating comfort and as per review it would be good decision. In the last 3 months I have driven this car 2500 Kms to long drive to Shirdi and awesome driving experience I was driving continuously at 85 to 90 Km speed.
The car can even reach easily 100 to 105 but as safety not advisable to drive above 100km.
Overall, experience is too good, we were 5 people+ 2 children in car and with luggage still all are very much comfortable. AC is too good. In a single day we drove 461 km Thane - Shirdi - Thane without any issue.
