How much does it cost to repair an exhaust manifold leak? on 2000 Volkswagen Jetta

The car is for sale so I don't know much about it. What's the worst case scenario?

actually wouldnt cost you more than 30.00 if you know how to fix the problem. Usually the leak is do to the gasket find someone who knows mechanics and youll be fixed up in no tome...
