My craigslist rule is "first come, first served" no exceptions. I don't care how many times someone calls/texts me and says "I'll be there in an hour with cash", if you're not the first one here with cash, too bad, so sad.

The really sad thing you can't count on people nowadays to honor their word and/or be honest, doesn't matter if it's the buyer or the seller.

I've had people "show up with cash", inspect and test ride, then say "all I've got is 800" when you're asking a fair going rate of 1500. Thanks for wasting my time, see ya!
