Unfortunately I have yet to try a mark 6 GTI never mind a Golf R. However i'm sure the GTI will be plenty fast for me after having driven a nippy 1.4TSI. I love the GTI''s tartan seats and red stitching along with the red strip on the grill which takes me back to my mark 2 GTI.
As for the gearbox, manual will do me fine as I have read numerous reports that the manual is super slick.
ACC should be standard on a GTI at this price level.It will be when the mark 6 comes to the end of it's life span.
