This is the kind of reply I would send, if I dared...

Dear Jimmy,

Thanks for your offer, which is certainly very interesting. Before completing the transaction, we need to settle the following details.

a) A wire transfer directly to my account and originated by the future owner is the only acceptable payment system for this deal.

2) I will need proper identification of the owner to prepare the standard purchase contract we both need for documentation, tax and transport purposes.

3) In case an intermediary is to participate in the deal, I am willing to consider licensed brokers/brokerage companies only. I will also have to check if your choice of broker is acceptable and for this purpose the complete information about the broker - name, ID, registration, license number, etc. - will be necessary.

I trust those simple details will be easy enough to comply with.
Regards,

If it is a scheme, there will be no follow up.
