Radiator Shell

I hit a pothole and ruined my radiator, had it fixed, and now there are many more problems, what should I do?

I have a 1995 BMW M3, I took a road trip to Florida, but along the way, hit a big pothole, and the car started overheating. Luckily I was near BMW of Macon, GA, so I took it to them to have it fixed. I paid a $98 diagnostic fee, along with another $1000+ for a new radiator, at which point they told me the thermostat was stuck closed and would need to be fixed. After I shelled out all this money, I drove it back, problem free, to southwest michigan. After a few short trips around town, it began overheating again. I took it to the local bmw dealer and they said it was overheating again due to a leaking head gasket and possibly a cracked head, estimated cost to fix is $2200-$5800. Should BMW of Macon be responsible for this, as they didn't tell me anything about this, they told me it was fixed and safe to drive? What should I do?

I back up nj973man's response. Ancillary or consequential damage and *very* likely occurred at the first over-heating. I think it unlikely that BMW Macon has any liability in this. Even if they had performed a leak down test (and, who knows, they may have) they probably would not or could not have detected the problem. As you yourself have noted, the damage to the cylinder head wasn't noticeable until several heating and cooling cycles had passed and the damage had progressed.
