Is there anything I can do?

I won this car and picked it up on Wednesday. I emailed the guy and asked how bad the damage was and if it was driveable. Was told it wasn't bad and driveable.

So I wrote out a cashier's check and picked up the car. Looked it over and the paint looked bad, hood was pushed back a bit and car started fine.

I get home and pop the hood to do some maintenance and coolant sprayed everywhere from a crack in it. So I added back in almost a 1/2 gallon of antifreeze. Also the AC doesn't work, and last night it rain and about 1 gallon of water fell on me and the passenger seat this morning.

I emailed the guy back and mentioned all this to him and of course he said "Well the AC worked for us, and it rained yesterday and it didn't leak" and "the radiator wasn't leaking for us". Do you think this is BS?

What can I do? Cost of the radiator is about $100, and to fix the sunroof is another $100-200.
