I'll trade you my ____ for your Dodge

I had a guy trying my doorbell to ask how much I wanted for my Dart.
"What's the for sale sign say?"
"Uh..... There is no for sale sign."

Well there you go.

He starts telling me how great it is. It isn't.
"I brought my boss by to look at it!" And that's when I got pissed.
As I told him, it's all downhill from here.
