What am i missing??..

You can always PM the seller and warn them of the problem and give them a chance to correct their ad, sometimes they aren't knowledgeable enough and make an honest mistake.
Have you ever been cursed out for trying to help anybody out?..
We're dealing with the public here, and we definitely don't know what kind of response you're going to get even if you're helping out...
For instance, the time that I asked what made the chevy chavette rare??.. As the email came back completely cursing me out re affirming his claim in the ad that it had the original handbook in the glove box... And it was worth every penny that he was asking...( Which was completely outrageous and I will bet the farm that he didn't get it...)
This is only one example where I tried to politely understand The asking price. I'm just not confronting people about it anymore.. This is like one out of a hundred where I said anything because it was so gosh darn outrageous...
