Car Towed - what would you do? Need to give advice to a friend in need.?

My friend is having a series crisis. I don't have a car, so I don't know what to tell her. So, I'm hoping you fine people here can help give her some advice. Her car was towed in NYC by the Marshall's office because she owes $500 in outstanding parking tickets. She thought she had paid all 3 of them off - however went she went down to the Dept of Finance - there were penalties that were never paid because they were mailing the notices to her old address from 2 years ago and the post office wasn't fwd her mail anymore. The total she said she needs to get her car out of impound is $800 something. She is on Social Security Disability and doesn't have that kind of money. Plus the car is worth maybe $300. (She's says $645 - but I've seen her car.... it's NOT worth THAT much.) I can't fit all the details here, so please see my additional comments for the continuation and further information about this situation.
