The commercials say CHANGES EVERYTHING. How come? The car's called Indica Vista. Firstly, the name is the same apart from the addition of Vista. The design is inspired (in fact, is an improvement of) by the original Indica design. And it still offers the same thing that Indica offered: Space.
What's the need to CHANGE EVERYTHING? Perhaps the folks at Tata do not want to keep Indica attached to taxis. Perhaps they are not happy with the perception of Indica as it stands now - that of a spacious but inexpensive small car. But the ironically they are using the same name: Indica (perhaps to leverage the name). So how does it CHANGE EVERYTHING? At least not the perception of brand Indica.
But, what if it does? What if the consumers do come to believe CHANGES EVERYTHING? Yes, of course the price has gone up. The design has become better but then perhaps it's not really that great when compared to other brands in the segment. The argument can go on. But what Tata might end up losing the strong positioning of MORE CAR PER CAR. Yes, that's what Indica is. That's what sold Indica in spite of all the problems.
On Indian roads, size of the car really matters. Small cars won't lose favour for a long long time to come. But with that the requirement for adequate space is also not going to go away. MORE CAR PER CAR is what made Indica, is what gave Tata a foothold in the India car market. Invaluable and lasting position!
Tata had better not change anything. Simply make the same thing better.
