This letter has been going around for a few weeks now to all kinds of ads.

If they do not mention the specific item I am selling in the text of the message, I never respond. If it says "your item" or "the vehicle you have for sale" it is definitely a scam.

I always say hello in emails. 1. It is the polite thing to do. 2. If I come across as a nicer person than someone else interested in something I want to buy, there's a chance (albeit maybe slight) I will get it over the other person because of that. 3. I hate receiving emails that are written like a text message, you have a keyboard in front of you, use it properly. If I get an email that looks like it was written by some wanna-be-gangsta idiot, I don't even respond.
