Towing Issues: waiting for tags from State and car towed with no warning, insurance policy number, storage fees

Question
I live in Philadelphia. I was ordered by the State of PA to send in my tags and registration for three months as a penalty for not having insurance after 30 days. So I parked my car in front of my house and removed the tags and sent it, along with registration, to the State. I received a ticket for no tags by the local police. I contested the ticket and placed a sign in the car (front window) explaining that I was waiting for tags from the State and showing my insurance policy number (car is still insured). One day I came back and noticed the car is gone. If the City towed it who is responsible for the towing and storage fees? If the city crushed or sold it how do I get the value of my car back (Honda Civic 1995)? What are the chances of me winning a case if I sue the City of Philadelphia for improperly towing my car and disposing of it? What should I have done to prevent my car from being towed (besides not getting in trouble with the State in the first place)? Thanks.

Answer
Wow, if I understand this question correctly you lost the "right to have the vehicle registered and licensed" for 3 months...

Then you parked the vehicle on the street in front of your house.  

Now if I got that correct, I am ready to try and help you...

You talk about the City towing it (guess these are the guys from the TV show "PARKING WARS") and unfortunately I do not know the exact time frame of it being towed and your being able to get the tags back...

That might be a key here, but again it does seem that the vehicle was "unlicensed" at the time of towing.  After watching the TV show, I came to the conclusion that it has to be licensed and the whole underlying issue is "REVENUE" for the city...

Now the responsible party for paying for the tow would be you the "legal car owner". All towing and storage fees are your responsibility.  

Now if the City has sold your vehicle or had it crushed then it must of been there for an extended period of time.
They do have a process to follow in order to gain "legal authority" to dispose of the vehicle in either manner.

Now as to winning a court case against the City, well that would depend on how you present your information and have documentation about the issue.

And then it depends on the judge as to if you win/

As to what you should of done to prevent it from being towed in the first place... Things that come to mind for me are public storage units where you can park the vehicle, a friends house (garage), or even calling a tow company and seeing if you can store a vehicle there (which they will charge you for, but not at a full rate at times)

I hope this helps.
