This is a CON.

They contact everyone in Autotrader and claim that people are waiting to buy your car/bike/van etc and for a small fee, normally around £79 they can pass the details on and you will see your car.

DO NOT be fooled. There is NO buyer. As soon as they have your money you will NEVER see it again. Its a bit fat scam and still many people are stupid enougth to fall for it.

There is NO buyer. Save your money and run you ad for a few more weeks if no one calls. (except these cardata fools.)
