Oh I forgot, option 4.... f*** it, order it now, get a new GTI and drive around going zoooooooooom about 3 months sooner

If it was me though, I'd be going for one of the others despite #4 screaming at me to drop the coin!
Although if I was looking to outright purchase (not PCP or PCH) then facelift all the way, but you won't know what that will be and what extra things it might include for some time though - I'd guess maybe digital clocks, LED lights, different DRL's, couple of different colours and maybe even 7 speed DSG might be on the menu though...
