Blown Head Gasket on 2001 Dodge Stratus

Im planning to purchase a car but it has a blown head gasket...how much does it cost to repair? Will the sealant work? Should I buy the car?

well if it is only the gasket it should not be a problem but it is never the gasket by it self i bet u the head it self is damaged too from over heating and that can cost you
there is a lot of reasons why a head gasket blows/ need to be check out good ,have one in shop now over 1200.
