Why not post a picture of your "for sale" item
depends on what you are selling aswel, is it something special or do we all know what it looks like?
new or used?
price is a big one too, if its a 20 dollar part, ill take your word for it if your trying to sell a 40 plus year old, 1 of 35, numbers matching 383 FIVE SPEED ragtop cuda for a measly 89K...I might want to see a picture or two
