Hi James,
Im a fellow manc on the lookout for an Edition 30 as well. Im currently own a MK4 V6 4Motion and was considering going the the MK5 R32. You honestly cant beat the gorgious sound of the V6 engine but on paper, the ED30 offers so much bang for your buck with considerable gains when it comes to tuning.
Im not sure to the answers to your questions as im sure some of the owners will be along to shortly to help you but from the research ive done, asthetics aside (the interior is marmite), the ED30 is defo a special car!
Ive been searching for 2 months for my ED30 but im holding out for one which tick all the boxes for me - i.e on spec and extras.
Good Luck James
Rich
