Ask HN: How to Retrieve an Expired Posting on Craigslist

I recently bought a car on craigslist that I was told was not in an accident - only to find out it was (the family confirmed this, but the seller had lied to me). His craigslist posting had said the car was not in an accident, I want that posting that I can't find now! (Shame on me for not getting a mechanic...)

Can I talk to a real person from Craigslist? How do I retrieve the posting? Any tips on my situation. It was up between end of May and end of June. It was reposted twice during that time.

The resources online have largely revolved around being the one who put up the posting. Search engines will not archive (most of them) Craigslist postings.

Edit: I've already gone through Craigslist's help form, but that's largely ineffective, except for giving an automated message and faq.
