Yeah, if you don't believe us, there is a test that a shop can do that tests your coolant for contamination from exhaust gas, if it comes back positive = blown headgasket for sure.

I would walk away unless the car is in great condition other than the head gasket, and make them get it done by a good dealer/mechanic and warranty it.

If they did it, they might just pull the head, throw a new HG in and call it a day, and if the head is warped (if it overheated the head, more than likely it is), the head MUST be machined for the seal to hold properly, hence why I say get a warranty.
