I would like your advice too on how to proceed with getting my car back from impound, minus the impound charges if possible! Can you point me in the right direction? 

The car had temporary ‘plates’ that I had made myself to indicate it had reg (RR-082), the car had ‘Private Property Notice’ signs clearly displayed too (see attached). Unfortunately I did not take any pics – silly me.  

Contact the impound and they will tell you what you need to get the vehicle out… just pay the extortion money for now and we will sue them in due course.
