Continental GT service intervals

Looking at getting an earlier car (04/05) and my main concern is comprehensive service history, of which I have no clue what that is.

What is the maintenance schedule?

Many thanks

Is it oil and filter every 12 months regardless of mileage?

Seems many for sale claiming FSH with '6 stamps in book". At 2004 it should be 10+ surely...

Surely it should cost most around £50 on windscreen excess... ;-)
