re: the person asking about optional extras.
if you can prove they are factory fitted, there should no be a problem as in effect these are classed as "standard". aftermarket items, are not "standard" and therefore need to be declared. even alloys. even if they are ford alloys and you own a ford car. if they did not come from the factory, you have to delare them. even little things, like spot lamps or clear rear lights. some insurancecompanies even throw a hissy fit if you add valve caps! cosmetic changes, although they do now make you car any quicker, they enhance the look of your car, therefore making it more of a target for theives. this is why you must declare everything on insurance. if they didnt want you to, they would ask. although you may want to check with your insure what you are and are not to declare, as some companieshave different views, so don't take anyones advice as set in stone - you really need to speak to your insurer.
