Bingo. I haven't made real money in an auto industry since 2003.
If you're here to be entertained by others' misfortunes or ignorance you should just watch Tosh 4.0 and surf YouTube - you'll get more out of it.
If you're here to add to your shops workload and add nothing more than self-promotional threads that detail nothing a DIYer might find useful you would be better served to spend money on real advertising at local tracks (assuming your stuff is winning), contingencies, and signage.
If, however, you have an opinion or technical info to add and can communicate and interact in a positive and respectful way - jump in. Nobody's right all the time.
