Auto body repair & detailing: Sunroof, wind leaks, bombay india

Question
I am from Bombay/India.What is the purpose of a sunroof? If sunroof sealing is not proper it will be leaking from the roof in a rainy country like mine? Why have this additional menace to deal with?

Answer
Obrien, it just goes to personal preferences. Some folks like the sun glaring down on them at all times. I do not. I agree, having a sunroof opens you up to hassles like water and wind leaks, but a factory installed power sunroof add a lot of value to a car. Bill
