When I listed my car with Mercedes in the description, the majority of the responses were spam. When I listed some old computer parts, there was almost no spam.

I suspect the spam/scam artists search key words or terms that connote wealth and then they go from there.

On the flip side, I don't understand sellers who make it darn near impossible to contact them or to see the item. If you're not interested in selling, then why list the item? I had one guy selling a run of the mill table and chairs, $30, and it took four e-mails to get an address.

Q. Where can I see it?
A. I'm on the NW side of town.

Q. Me too, near [named major intersection]. What's your address?
A. I'm inside the loop near the Witte.

Q. I'm interested and have cash, but I need to see it tonight since I'm packing my daughter to school tomorrow. What's the address?
A. Are you coming right over?

Q. Yes, if you tell me the address I'll come look at it right now.
A. Okay, I just wanted to make sure you were serious.
