Great cars, just picked up my second this week after buying one new back in 2008 and then regretting selling it. There's lots to choose from, I looked at many, the service history of some were shocking. Cambelts were originally at 120k on launch but these got revised by VW later to 4yrs and 60k I believe.
The DSG is a fancy piece of kit but I've always preferred the manuals, I also like the standard seats to the leather. Find one in spec to your personal preference, Xenons are nice, Centre armrest very useful. Air con compressors can go wrong and make sure it's had the various recalls done.
