My local dealers were quoting 6 months - I suggest you go to the Orangewheels web site to get a discount price for your config. If you like the price they will refer you directly to an authorised VW dealer - Inchcape in Swindon is one but they use others - who will handle the deal directly, they pay Orangewheels not you - you pay deposit and deal only with the authorised VW dealer.
I am buying through Inchcape and they sell so many Golfs they have a series of orders already placed which on they can modify the spec on as long as they have not yet been built.
I ordered a fully loaded 5 door DSG on the 5th of September and have been given a firm delivery date mid December - and they have agreed registration in January to make it a 2016 reg.
May not be the closest dealer to you but the discount saving and early delivery is worth the compromise and service and warranty is valid at any VW dealer so no issue there.
