Been my experience, if it seems to be a great deal, you have to jump and not hesitate. I know it's a hard thing to do sight unseen, and if it's local to you that gives that person a big advantage. I've bought cars for 30K plus sight unseen with just a few pictures...sweated it out till the car showed up on the transporter and it all came out good. Sometimes you just have to roll the dice to get a great deal.
I hope you find something else, this is a buyers market right now, lots of good deals for someone who is willing to jump on a deal.
