do any of you guys think there is any mileage in persuing the argument
Not a hope in hell I'm afraid!
Thats just what VW do. I'm also a member on a Scirocco forum, and there are many p1ssed off people there who've just recieved there 2.0TSI 200bhp, to find out that now VW are supplying it with a 210bhp version (the same as MK6 GTI) as of build week 45. There are still people waiting for cars to be built in like week 43 etc - who won't get this upgrade! It really sucks - but thats just the way things happen.
We probably won't see the LED rears here for another good few months on a GTI. They're not on vw.co.uk yet - so its unlikely we'll see them this year.
The next thing is going to be the keyless entry / start button - which was showcased on the Golf R in Frankfurt. The first batch of R's won't have it - but afterwards it will be an option (or perhaps standard?). I don't think VW will recall the current R owners and retrofit that either I'm afraid.
