I hate the automated answers as much as the next guy. But I'm not ignorant enough to give a smartass answer. After all, this is a potential buyer who is just using a tool of convenience.

And sure, I've seen those "if the ad is up its still for sale" ... and not gotten any response !! So, if I'm interested in something I ask a relevant question and I don't expect any smartass answers from someone who basically wants my money !!
