I am not a person with a lot of pride, no problems here with being put in my place when I'm wrong. But as I write this I have won my battle today.
My pizza beater got a flat the day before Thanksgiving so I needed to get it repaired. I figure while I'm at it the $500 miata could use an alignment. While at the counter talking to the sales guy, I ask if they can do the alignment to spec, to which he replies only factory spec. My reply is while I don't know the factory specs I do know there is some tolerance allowed, could he have his people set it to the maximum caster and camber allowed and the minimum toe within factory specs. His response is that everything is supposed to be 0, at which point I get a puzzled look and reply can I see the specs your computer has. He digs around for a minute and finds them. Low and behold nothing is zero and there are tolerances. At this point I've won and say that I would like everything set to these exact settings and hand over my key.
It is just really annoying when you are being told you are wrong by someone who doesn't have the slightest clue what they are talking about. End of rant.
