Thanks everyone, for your advice and making me feel so welcome.
I have other (personal) reasons for waiting until March but after reading your posts, they seem to matter less. And I plan to keep the car for a bit, at least four years, so I shouldn't get too hanged up on the reg. thing. I was even considering getting a GT11 plate, but I've come to my senses.
Yes, I have ordered the Xenons. I am pleased to be getting the rear LEDs and not too bothered if I don't get the front DRL LEDs. I think it's probably my favourite combination, anyway. But you have reassured me regarding the early arrival, thanks.
As for the travel from port, I guess I just assumed that there must be some backlog. The dealership is in Manchester and so weather has been an issue. I will probably ask about it anyway.
So I'll think about it and then make up my mind but I don't think I will be able to wait. I'll keep you posted. And I will post a picture as soon as I get my hands on it. It's shadow blue, with 18" Monzas. Not many pictures of them around. I've had to make do with VW Germany's configurator.
