OP here. It's been two weeks since the accident. GEICO thinks the car is repairable. I will let update with the total costs to repair when I have that information. The Blue Book is $33,000 and repairs are thus far estimated at $17,000.
The fluid leaks are all coming from the broken radiator -- transmission fluid and water. No engine leak fortunately.
Anyway, I'll let you all know how I fare out of this. I do hope it's fixable actually and would rather it not be totaled. I could not afford to replace this car new and don't want to go the used route.
Thanks all for your replies thus far.
