Check out this guy selling a 72 Duster.

Its probably his attempt at minimizing the hassles of selling a car. I see his point. How many times do people phone and ask questions answered in the ad or for your address without even making an appointment? Lots of guys like to collect pics but have no intent of buying. For a local sale I would do the same - ask a few questions and come and see the car if you are serious. That said, if there is too much attitude it just turns people off from even calling.
