No one wants to be misled. Be as honest as you can when listing an item. Don't list features unless you KNOW they are there. That way, you'll avoid any possible misunderstandings in the future. Be objective in your evaluation of your own equipment.
Most people are willing to pay for an item what it is really worth.
Warts and all. Take a look at it from another person's point of view and list it for what it is and how it looks. Elaborate on your description. Your potential buyers will only know what you list in this section. Be open and complete in listing all the options, features, software, hardware, etc.
