Since Oct 2010, I have been driving Tata Indica Vista Quadrajet Aura, in Kolkata, where average speed is 15 Kmph! But I am getting about 14 kmpl, Long highway driving so far not tried.
I have done 4800 kms, only one service done, waiting to see 5000 & 10000 service and results thereafter. I received multiple calls from Tata Motors, asking about any problems I am facing, good followup work by Tata.
For a short trip I have traveled on highway, at 140 kmph the vehicle was extremely stable and smooth. The engine is free from sound and vibration.
So far I am happy with the performance.
