Focus non-servicable parts ? Advice please !

Hi all, I have year 2000 focus 2.0l petrol. Does anyone know what, if any part on the car would be classed as non-servicable in insurance terms ? It's a long story but I need to find out what is and what isn't ?

Thanks

A car would have hundreds of non-serviceable parts. You need to be more specific about the situation.
