You know when you go on confused.com etc and you put in what car you want to insure it says (for mine anyway):
Astra Sporthatch 1.6 SRI Turbo
Astra Sporthatch 1.6 SRI Turbo XP
Mine has the XP and the 18'' penta wheels but they were fit by the Vauxhall dealer when I bought the car so my reg comes up being a non XP car even though it now is... I told my insurance this year and nothing changed so Im not bothered about that but in the future do I need to change it somehow, especially if I insure my car by the internet and dont talk to anyone which Im panning on doing as its much cheaper this renewal? Its still standard I suppose...?
