I did think about waiting for the PP but not on the basis of it coming with a 7 DSG, I was informed it was for the diff and power upgrade.
But based on price and how often I'd actually make use of it I decided against.
I guess what I need to decide now is, is the 7 speed box really going to be of noticeable difference over the 6 for fuel economy etc while cruising along in a GTI. Unsure next steps now.
