So I talked to the vet, the surgery went well and Barney is zoned out from the drugs - but he always is like that when he is tired. I will be checking in with them again tomorrow and then home Friday.
As far as the car it is not looking good - I haven't heard from the dealer but was doing some checking online - and found that it can cost $7,000-$9,000 to fix this (and yes, that is not a typo, that is thousands). I am completely freaked out and hope that the dealer has better news then that - at that cost I could almost get a new car (and believe me, I do not have that kind of cash handy, and since I don't use credit I will be totally screwed if this is what it ends up being).
I won't be posting anything until tomorrow - I am really just too upset at this point to do much. Hopefully tomorrow will be better.
