I'm also very near Fairfax. LMK if you need me to check it out.
Two questions, though: did you find this car advertised in Florida, (say, your local Craigslist), yet it's in Fairfax? Does the price seem ALMOST too good to be true?
If you answer yes to both, it's a scam, and when you ask to send someone to see it, he'll tell you he's left the country and either the military or EBay is going to ship it to you, and that there's no way anyone here could check it out. This story is a scam, don't believe it for a second.
Good luck
