Hi CraigW.
Just nice to have, and although fast delivery is desirable, I am able to suppress those "now" symptoms so as to get the car with the additions that I want.
I ordered my car with no extras and it will still have been a 23 week wait if I get it this weekend (due to some "priority shipping" considerations because I had an email moan all the way to the top in VW UK).
Where are you getting yours, or are you still shopping around? If you are shopping around locally, i'd skip Benfield Silverlink and try Benfield Scotswood Road - they're much more receptive to a haggle. Similarly Sunderland Pulman seem more receptive to discounts than Durham Pulman, and the you have Lookers down in the Smog. Discounts are really tight right now unless you're going through a broker (but you'll almost certainly get a significantly poorer p/x value).
