^^^I've seen the same car up close around Brum. Seems to be parked up not too far from me. It's defo not an edition 30 - just looks like one. Moneysupermarket.com states it's a GT TDI. Not sure how accurate it is.
There's been a surge of MK5 GTIs - the first surge was around 2008, when the early 05 models would have been traded in. The second surge seems to be this year with more 06/07-plates being spotted.
