I kept waiting ... and waiting - then called customer services who said I had to request a number !!
It was sent through - number 2069 .... about 2 days before I sold the car having had it for 18 months .... poor service on VW's part.
They don't like to talk about their 'limited' run of 1500 cars
TBH the number didn't interest me (after all, if they had stuck to 1500 I wouldn't have had the car!) The whole situation is somewhat amusing though .... in a strange kind of way ....
