Parking is expensive and irritating in the city, I thought I'd start this topic so that anyone who knows of or finds free/cheap parking in and around the city could tell us here. (if possible provide addresses or GPS coords)
Mate, if you can afford to have a car, you can afford to fill it up with petrol, and pay for parking!
Print out the attached document and keep it in your car. There are hundreds of free parking spaces arranged by areas and street name. Unfortunately mostly in Chinese and also no GPS coordinates but it might still proove helpful.
Personally, I do it the Chinese way and park somewhere in the street in front of my house, shops and restaurants blocking the right lane since my building does not have enough parking space. I read that Shenzhen has 700,000 parking spaces for 1.7 million cars, i guess that is why the police lets me get away with it.

Mr. Sterzel, this web page (http://goo.gl/IGVHL) from Traffic Police Authority would be useful to you.
