They should have added few feature in their products and then increase the prices...Doing so customers would not have pissed off; and they could have increased even more and the increase would have treated as justified and need of day...
Say if 25k was the need of the day; they may increase by 50k after giving either NAVI/LCD as standard (the unit i am sure is costing them under 25k) OR adding fog lights and 2DIN audio /w 4 speakers as standard...
