^^ Oh man--never thought of that ("freeing" cars from the police impound)! lol
Of course you get an automatic three-star wanted level when doing that.
Do you have any idea as to whether those cars are then genuinely clear of the impound fee or are they just outside the impound but still 'regarded' as being inside?
I'm not completely(?) sure this has been taken into consideration by Rockstar yet. lol
