An aquaintance uses RS246 (I think thats the name).
Its got a nice ring to it but Mk567GolfGTI.co.uk i'm not so sure?
TBH if you have a problem in your Mk6 GTI or R coming on here, you could always set your own forum up
Anyway a Mk6 is just a Mk5.5 anyway
Just joking but yes the Mk6 site has been a bit dead maybe pull it down?
