Best Answer

go to a dealer or trade the car off. (seriously)

I agree with this. Cadillacs that start leaking like this are 99% of the time leaking from the rear main seal. You have to pull the engine or transmission to fix this. It isn't worth it unless you really, really love this car. It will cost you a bundle.
