I bought the Nano twist, and I must say it is an amazing car, totally underrated in India.
Very spacious for 4 people, and Im quite a big guy;)
Awesome for daily office compute, especially in Indian city traffic.
Very good Air Conditioning.
Audio system along with blue tooth connectivity was an unexpected surprise, as well as central locking, power steering, remote locking and powered window sliders.
I hope the next model, comes with airbags, and they fix the issue of the radio turning on, every time the engine is started.
