Selling a car on Craigslist

[Psurfer]

I wondered about the same thing yesterday- when browsing CL, I saw a nice expensive late mdl Porsche offered by a private owner, asking price of probably 20x the OP's. I thought if it was me doing the selling, I'd take photos of the buyer and his drivers license, telling him I was simultaneously emailing the pics to friends as security, figuring that might at least give me a read on the guy's face to guess if he was planning anything funny...
