as you state theres some uneccessary posts on for sale threads , however everyone is a potential buyer , if in your advertisment and that of others you can explain in as much detail possible any forseable question that might arise from prospective buyers , then ask for the thread to be locked then all questions or further information can be done via private messages. You can save your private messages and copy and paste if repeating questions to members or the alternative is to have some questions arising that may be dificult , it is entirely up to the vendor to choose to answer these questions , as you have state you have no quarms with answering as nothing to hide this will however give the sale better credence as your honesty and integrity are the very first part of any sales pitch .
