it looks grey inside the car, I think its just the light or the flash.
As for the "highline"?? I think this is where the Aussie ones are different. All GTi's come standard like this in Aus (apart from the sunroof, DSG, bi zenons, leather and iPod adapter I had added)
I'm going to give it a god wash this weekend and take some really good photos so you guys can see what differences there are if any.
