Paperwork only states registration date of 13/10/07. 06 is not mentioned anywhere.
The Service/Warranty book does not have a sticker or place for it so I guess it's different in the UK.
I did get the bike cheaper but thought I had just haggled a good deal on a new bike and never even thought it would be an old model. It came from a very well respected main dealer. And, to be fair they do seem good. Maybe it's just an oversight on their part as I can't believe a salesman would do that on purpose
Anyway, I will let you know the outcome.
