Thanks for all the input guys.
I am really surprised that VW don't offer this colour in the UK surely they could drop one of the silvers and give us at least one wacky option. I am bored with all the monochrome colours german manufacturers seem to offer nowadays, at least companies like ford do give some unusual options.
I will pay the dealer a visit and see what he thinks, if I have to pay circa 1.5k for the blue I think I will bite the bullet and go for it. You never know it could be quite sought after come resale and I may be able to claw some of the cost back
