So if you can prove that the credit card holder participated in the sale...........read my previous post regarding citing the card...looking at the name on the card, recording the expiry date and 3 digit security card on the rear of the card. citing licence.... correlating the name on that licence......correlating the name on the registration transfer papers to the credit card holders name and signature.......simple...

How would you know that that was the credit card used to fund the PayPal payment?

Just curious.
