hope you get your money, and definitely take this to the fraud prevention dept at your local poilce and let them look into it. It sucks that the cops didn't even bother and just wrote you off just because these guys claim they're from Hungary.Update:
The buyer wrote me that he has nothing to do with it and that it must be the driver´s fault. And he will send me the 700 Euro asap! Weird!? If something like this would happen to you would you send the seller another 700 without discussion if you are not guilty??
