The forum needs a feedback/trust profile. Where if you make deals with someone you can choose to give positive or negative feedback. That way you know who your dealing with as you would expect someone to buy a few things before selling a few, etc.
There was another guy on here who lied about the reason for selling his Z4 saying he needed the cash for a holiday / he was going to france for some time, etc. He sold it to someone on here then the next day put up a wanted thread for another Z4 within 24 hours.
Now I wouldn't want to be the guy who just bought that Z4 where the owner said he was selling it because he needed cash desperately and then the next day is looking to buy another.
Stay safe folks.
IMO the mods should ban both. As they clearly aren't trustworthy.
