I don't think I am missing the crux, but you're right that we're talking past each other. The point I am trying to make is that if you had left it at that - that it probably wasn't a fault on the car, and not added the bits I highliighted (which didn't add anything useful to your post) then I'd have not problem at all.
Re-reading my post I see that it is more aggressive than it warrants - frustration was what made me post it, not aggression, so I apologise for that, and for that fact that instead of us now being able to discuss the issue, you're pissed off and there's not much point in us doing the usual internet argument thing where we each repeat ourselves and go around in circles.
