People who talk out their ass about a topic they know nothing about.
I went to pick up some doors/bumper for the MKIII from a guy in Cooperstown...here's a few snippets of our long conversation, halfway through I gave up arguing and just listened because he was making an ass of himself:
Him - "Yeah this MKIII right here I'm building is good for 600 hp, just have to finish the body"
Me - "Wow, what's it got in it?"
Him - "Well its a 3.4L built with a full Brian Crower rebuild"
Me - "...oh. Wait, 3.4L? So its a 2JZ? Nice"
Him - "No its a 7M"
Me - "..."
(he pops the hood...spearco IC, stock 3000 pipe, CT26 sized turbo sitting on the stock exhaust manifold)
Him - "Yeah, its a Greddy (or something) turbo with a different wheel in the back, and they bore out the front. Greddy IC too"
Me - "OK"
later....
Him - "But a full standalone is really the way to go"
Me - "True, but piggybacks have come a long way. They've been used for decades now and they're easy to use"
Him - "Nah, my friend had a greddy blue spec and can't get it to run right"
Me - "...blue spec?"
Him - "Yeah, blue spec."
Me - "...you mean an emanage blue?"
Him - "Err, well, yeah."
Me - "Yyeeeah, you have to have a running car in the first place before you put a piggyback on it otherwise it won't work well, I can't imagine any other reason it won't work"
Him - "Well they're still not the way to go."
Me - " have an emanage blue on my car, I got it running in an hour. Its easy if you know how to splice wires"
later, getting more frustrated...
Him - "(stuff here)...but a metal headgasket is the way to go. You went metal, didn't you?"
Me - "Nah, just went Toyota with ARP st-"
Him - "You mean felpro?"
Me - "...no, I mean TOYOTA."
Him - "Felpro."
Me - "Toyotas gaskets are not felpro."
Him - "Yup! I come from a line of Toyota mechs, I know."
Me - "Yeah, ok"
after that bullshit...
Him - "But if you ever see an ignitor -- you know what an ignitor is -- you should pick it up if its cheap, they can't make them any more!"
Me - "What?"
Him - "Something inside them, they can't physically make them any more"
Me - "I see them on the internet for like twenty bucks used, there's nothing complicated about them"
Him - "Well they can't make them any more, so if you see them you should pick it up and just stash it away somewhere!"
Me - "I'll do that."
God damn it it pissed me off, but I really needed the doors so I didn't argue.
