Similar to mine I guess. I've got one of the oddball pre-WLTP MK7.5s before they shut the factory and order books.
I'm assuming like this...
VW push along a load of cars with the customer orders and stockpile them. These are all registered and given to VW staff to run around in, which are then dropped into the dealer network. Sorry, Sir, we don't know when you'll get a new one, why not have one of these??
So, there'll be a load of the last batch of GTIs to tempt people into rather than waiting for a MK8 GTI??
