I would suspect faulty heater core or failed heater hose. Head gasket failure will not leak coolant into vehicle. When a heater core fails, it WILL leak coolant into the floor, usually passenger side. May also notice slight filming up of the windshield with the heater defrost on high.
For estimate purposes, is your vehicle the sedan or convertible style?
