2001 Buick Regal Coolant Leaking

Coolant appears to be leaking under the manifold. Does this mean the intake manifold needs to be replaced? Is this comon in these cars and is it a big deal or should I look into buying a new car?
Right now the add coolant light is coming on every 3 or 4 days for me to add water/coolant. Thanks
