Only the Premium GT models come with the screen and suede leather interior. definitely nicer to have, however it is usless because you cannot play dvd's or use the existing navigation unit. It can be replaced for a cost of around $2000 to have it to Australian standards, however this replacement unit comes with DVD player including divix, mpeg, mp4 fricken spiff-ex if you want! haha, j/k. but anyway... everything is possible, just need to put your mind to it. something I can't be bothered doing!
As far as the car is considerned, one of the best cars i've ever driven, for a car that uses only 7.4l per 100km , it's a rocket! beats GTS turbo's , HSV's etc. for a non turbo, performs exceptionally well. Rated at 230kw apparently.
