IF YOU ARE SELLING THEY ONLY NEED YOUR EMAIL ADDRESS BUT
SOUNDS LIKE THE BELOW SCAM, READ IT AND SEE...............
They encourage you to accept a 'direct' Paypal payment and don't quibble on cost saying they can't view the item as they are disabled or working abroad etc etc but they will arrange a shipping agent to collect it.
You will get/got a "fake" email that looks as though it is from paypal.....it isn't because they don't actually have a Paypal account and have no intention of paying you. It will say the buyer has paid ...you won't have been paid.
If the item requires shipping the 'fake' paypal email will tell you that the buyer has paid for the item + shipping costs but you must send those shipping costs to the courier/ shipping agent via western union, moneygram or walmart etc BEFORE the funds are released to you. They are not interested in the vehicle, they just want the western union etc funds and you will never see money in your paypal balance.
They also 'sometimes' threaten legal action...have a laugh at that one and ignore it as its rubbish.
Paypal do not tell you to send trackable, they advise it for selling protection but it is not compulsory. Paypal NEVER expect you to use a rival money transfer service eg Moneygram or Western Union etc. Also their is no seller protection on paypal for any type of motor vehicle. Delete any emails and ignore the scammers.
