Douglas if you search for windscreen in the search page you will find many entries for new car cracked screens on later models. Probably best you have a little read of these first as background.
I currently have my 3rd screen in service on a 4/4 Sport 2009 with 17,000mls. - One screen on insurance - one replaced at dealers by factory.
Good Luck
