Is there any way to track down an expired Craig's List posting?

I’m trying to find an archived copy of a post I made in March 2008, and all I have to go on is the title, a few key words, the date, and the anonymous email address they assigned me. It sounds like a lot, but since ads expire every seven days I’m not having much luck finding it.

Any advice on a way to track downed a cached picture of it? Thanks!

sometimes you can find them on cached google pages. not sure about images though.
