i had one quite a few years ago now,before the scams were well known.

i had fully rebuilt show condition s2 turbo for sale on ebay.a guy emailed me saying he was part of the group who organised the paris-dakkar rally.their company was based in canada and they wanted the car to show in their headquarters there.i wanted 5k for the car and he said he would send me a bank draft to cover the cost of the car plus the shipping to canada but the draft would be sent from his base in africa.the scams werent too well known at this time and although i was suspicious i went along with it just in case it was genuine.
a few days later a dhl letter came with a lloyds tsb draft for £8000,i was to put this in the bank and then when the shipping co contacted me,pay them the £3000 shipping.........
as it was a tsb draft from a branch in london(?),i took it to my local tsb branch (who i bank with),and they said it looked ok-i explained the circumstances so they looked a little deeper and it turned out the branch had been closed for 2 years!
same day i get a witheld number from an african guy wanting me to pay him £3000 out of my account,he could barely speak english.i took his details and took it to the bank.they interviewed me and told me there was a lot of this happening now.
he rang me again a day later asking me wether i had done the bank transfer and although he could barely speak english,he understood FUCK OFF!.........
