Remember folks, quite a few who post items for sale here are not club members, or are not versed in the ways of selling. I would not expect someone to include things like trim tag information in a for sale ad...instead...if a potential buyer wants more information, they need only post a question or email the seller directly.
We're all aware of what goes into making a KF "right", but there are great many out there who are only interested in moving the car, part, or whatever along to a new owner.
So, let's not put requirements on what needs to be included in a forum ad - if we do I can guarantee a fair number of folks will go elsewhere.
And, yes, I know that occasionally folks do not respond to requests for more information. If that happens then it's their loss as they've ignored a potential sale.
Lastly, anyone who asks for an opinion about the condition of an item for sale is getting just that, an opinion. My version of a "nice car" may not be the next person's and I have to believe that most people understand that.
Just my two cents worth.
