They had to do so. I am not surprised by this. It was expected from Maruti because they know Indians very well and price accordingly. The cars which they had overpriced failed.
Nishant is right, I think we should come back to the point. One last note : Wise buyers (who know ABS will be mandatory later) will not take any non-ABS models. So MSIL better price it wisely. Do you think they would charge more money for the engine tune they made? It's hard to tune any engine to it's max.
