I'll throw a few pence into the hat also.....
Option 2 for me!
The MK7 and 7.5 are not much of an upgrade over a MK5. I'm sorry, but they are not. I'm not one for being won over by softer plastics and thicker sound insulation. The driving dynamics are more important. Look at the interior for example. It's all very familiar isn't it, apart from the silly digital dash which is a 4 figure bill waiting to happen. They are not much different to drive either, and have even less steering feel. WAY less.
I was considering a 7.5R but I think the MK8 will be a bit more of a noticeable leap forward over the MK5, instead of just hopping from one lily pad to another.
I'm also waiting to see what VW are going to do with their damaged reputation. Cheaper deals, more standard kit, better warranties etc etc? Might be worth waiting. The far east have caught up with the Germans and are about to surpass them very soon, so that might also be a viable alternative.
Anyway, I wouldn't blow that capital on borrowing a 7R. Manuals are heading towards the £15K mark now, which is doable with some savvy finance.
Depending on where you move to in the UK, hot hatches and fast Bimmers etc are theft magnets. Something else to bear in mind.
