Does this look brand new?

I agree with others, it's not even the dings and scratches as much as it is the dishonesty. If he lied about it being new what else has happened to the radio? Pricewise too, when I buy something used (even used only once) I'm willing to pay much less than if it were new.

I'd leave him negative feedback regardless of what he says or does to try and make up for it. Teach him a lesson.
