Generally parking is free and chaotic here, as long as you don't park completely illegal you'll be fine. As there are very little no parking zones it's not that bad to find a spot.
(All that needs to change because having a car is way to cheap and easy but that's another topic.)
As for the green thing, I have friends that drove their very crusty vw T3 with polish plates all over the centre for a long time (2 years?) before they finally got stopped but then the fun was over.
There's no cameras or stuff to enforce the zone at all.
