For all these cars to survive in India

Hi,
For all these cars to survive in India , i believe that the price of the car should be between 15-25 lakh range .
Cars costing too high are not that popular in India coz of a simple reason either we dont have that much of money and even if we dont have that kind of roads to drive this luxurious car.
These car manufacturers have their plants setup at Chennai , then why does it still have to cost so high
