Hopefully I'm wrong Snoopy but the same dealer that told me about VW taking the hit for the VW increase way back in September also told me that in general if your car has a build week of 49 or greater then it won't be completed until after the New Year!! However because of the demand for the Golf, they may work through that period for the first time ever, in the same way they never closed at summer this year.
He said the stumbling block was the other VW factories around the world, as VW liked to have everyone working the same to stop any bickering.
Again, it was only from the dealer so don't know how correct it was but he has been spot on with most things he told me.
