Also FYI if you would like ACC I know that on the pre-facelift 450h model it was only available on the Premier but it was an optional extra, just like the sunroof. However I do not know if it was even an option for the pre-facelift 300h Premier. Again hopefully someone else can clarify this.
I had all the technical and spec info relating to the pre-facelift cars (250, 300h and 450h) bookmarked but, annoyingly, these pages are now no longer available.
Good luck with your search Mark.
