That is true Illyun.
However think of it this way. It not only gets the car itself more attention but will solve your problem. At first you may lose slight value but in the long run once you have the placques etc the value will stay.
Alternatively. There are about three other editions out there and the MK6 GTi is on the horizon. I am not in the Uk but it seems that the MK5 is holding its value pretty well so far. So why would this make any difference?
IF you can get the placques before the MK6 GTi is released then you are safe. I reckon that once the MK6 is out you will become a "Black MarK". But then again. Without having the placques you are also a "Black Mark" because nobody believes that the car is special edition.
Either way. By pushing VW for this they might learn (Like Renault did) the hard way not to screw its loyal customers around.

SteveP- Nowhere did I mention the car or VW was crap. If you are sold a kettle that boils water in ten seconds and in reality it only boils it in 50 seconds and you payed a premium for that kettle. Would you be satisfied? Of course not. You paid a premium for the Edition 30. Yes it comes with colourcoding, bigger turbo etc but you also payed because only 1500 were being made. Much like the kettle a brand like VW Should uphold their name and not lie.
