Thanks for all the comments. My last drive through town prompted me to act and I went for a DSG ED30. Its in super condition, 72K miles with full VW service history, every option on the list (Xenon's, sunroof, reversing sensors, MFD2, highlines, multi function wheel etc) and stacks of paperwork/invoices.
Regarding the Mk6, its an interesting question. Based on research, as I understand it they are basically a Mk5 mechanically (timing chain aside) with a heavy facelift. Visually I like the front, but the back...not so much. The Mk6 does seem to be in the shadow of the Mk5 and Mk7, it probably deserves more credit than it gets, but it does seem to be a little overlooked by comparison with less of a following. Maybe that will change with time...
