Maybe he wants to withdraw because his lawyer told him that his posts on this forum can be used in his lawsuit against the dealer that is the subject of his only other posts in this forum.
On the other hand if he is withdrawing because he was offended by some of the responses to his dealer complaints, maybe we (that includes me) should be a little less caustic. Some folks are not as thick skinned as others. We don't know what his financial circumstance are, or what other events are going on in his life that may affect his attitude. "The Internet is an ideal environment for the bully and the self-righteous – you can attack personally without being personally in front of the victim."
That doesn't mean everything posted should sound like a Miss Manners response, but being called a troll right out of the chute might be a little much. Especially when it appeared to me that the OP was mostly venting about the dealer.
It is my personal opinion that some of the regulars here give excellent advice on how to analyze a problem with a dealer, and how to make good business decisions regarding what course of action to take. It would be a shame to repel someone who is most likely to need that perspective, even though they are a little emotional about the problem at the moment.
Just say'n.
