Selling a British car in Berlin

This is a bit of a long-shot I'm afraid - but here goes...

I have an English car in Berlin which at the moment is just depreciating. Because of the quality of the public transport system I really do not need it and am looking into selling it.

About a week ago a flyer was put on the car saying 'Sell your foreign cars here'. I no longer have this flyer - but does anybody know anything about this, or have any recommendations where I can sell a British car?

Hello,
I just saw your add, and wondered if you managed to sell your british car in Berlin. I have a British car here and my English ensurance runs out soon and I want to get rid of the car. What did you do in the end?
