HI,
I'm from Aus too. I just took delivery of my new GTI, 3dr, Black w. Leather and Xenon's.
I can confirm that 3dr's are made in germany with the R32's (something about making 3dr R32's there too) and the 5 doors are manufactured in South Africa.
I wanted my German car to be manufactured in Germany which is one of the reasons I opted for a 3dr (that and they look better IMO!!)
I can also HIGHLY recommend the Xenon lights, they are definately worth it. As for the DSG, not a bad idea if you like driving an auto with a fun factor. DSG is fantastic and the technology is awesome (its in the Veyron for gods sake!) but at the end of the day, unless your driving it on the track or through the national park on the weekend you'll have it crawling around town in full auto mode which is a waste of such a great engine! (IMHO!)
The leather in the GTI's are not the best to be honest, I was expecting better but I wouldn't have got a GTI without it, it adds another level of class to the interior and bumps the whole cars class factor up a notch!
Happy motoring!!
