Nope - if they add something to the standard spec you get it. If they take something away you don't get it.This is interesting that cars built at week 22 get the spec changes... I think my car won't be built until then (I still haven't got a build date) but surely they can't change specs having signed off on a certain spec when you ordered the car? Don't get me wrong I'd love the newer specs I'm sure but doubt I'd be that lucky... How would you find out if you get the new specs?
If something that was standard becomes optional you don't get it either.
If something that you ordered as an option becomes standard they will normally give you a rebate.
