Nothing wrong with referrals, fellas. When I needed to find some parts for my grille, headhunter's "spam" helped me find a good deal, instead of getting ripped off by the dealerships. They're not that far away from me, either.
Now if he was abnoxiously posting "G3t teh w3sTc0aSt p4rtZ!!1!one! LoLz!1!" in every single thread.. then that'd be a bother. But if I had a pleasant experience with a salesman, I'd want to share that with all those that were in my situation, too. Wouldn't you?
