[Eric 951]

I have a potential buyer coming for my turbo this weekend. They are travelling from new york, and based upon the PPI results will either be making a deposit or buying my car outright.
My questions are what are the safest means for payment?
Cash--obviously(I have a counterfeit pen)
But, seeing as how the transaction would take place on a Saturday, how can I protect myself?
I have heard about cashiers' checks being forged, and am leery accepting a personal check.
My bank is open on Saturdays, but even if I recieve a check, cash it and deposit it as cash, I can still be open to fraud as the transaction may not get posted untill Monday(next business day).

Anyone have any pointers--I already plan on taking down the drivers' license information, and I have the phone numbers(whcih can be changed).

All help appreciated.
