Daveh129: Is your factory extended warranty already arranged? I bought it for my R, but as I only just ticked over 3 years, I haven't had a need to use it yet.
However, I have a Polo GTI+ incoming (built last week, but a 5-8 week journey from South Africa via Emden still to do) and intended to get the 5 year warranty. The new pricelists came out about a week ago, and the configurators updated - you don't seem to be able to configure a warranty addition, nor does it feature in the new pricelists for the Polo or the Golf. Unless it is a special request now, or an unintended omission, you may not have the option to get it any more. You used to be able to add it to your order at any time prior to the registration of your car (to get the fully comprehensive factory warranty extension).
