Generally speaking, what are the fees associated with retrieving a car from an impound lot?

...like how much per day, the towing, etc. Have not had too much luck getting info out the loan company as they will not disclose the locale of the lot until the arrears have been paid. Money may soon become available to retrieve the car from repossession, but need to know what fees there may be from the lot. Any info, without prejudice, is welcome, thank you.
