Pauls view was based on information the factory gave him (Factory view in your parlance). He stated that in his first post.
They shouldn't have disclosed that information to him. He shouldn't have repeated it on a forum, particularly to criticise the OP and support the factory. That's my issue.
For him to then claim that he was able to assess the validity of the work by merely seeing a car at the factory is frankly ridiculous.
As we're obviously going nowhere with this I suggest we agree to disagree.
