So basically what we are saying is it's a lottery

Spec everything and hope for the best ?
I remember when I was specifying my GTD at the beginning of 2013, no-one (not the dealers or VWUK), had any idea what was available and what wasn't. My order got screwed up as both the dealer and VWUK said Lane assist was available and that the colour MFD was a £100 option. Not only did the lane assist get thrown out 7 weeks later (as they realised then you couldn't spec it on a GTD), and as we now all know, the colour MFD was standard equipment. Seems 2 years on VW still haven't got their act together ?
Can anyone explain then why since mid 2013, the GTD (5 door DSG) has gone up by £1650 (5.7%) and the GTI (5 door DSG) by £1665 (5.6%) in less than 2 years without a spec increase at all ? This is especially since the Sterling to Euro X-rate has gone from 1.1478 on the 11th March 2013 when I ordered) to 1.3962 today a better X-rate to VW UK of 17.8% (surely the cars should be cheaper not more expensive) ?
