Welcome to the club, Dos.
Looking at what you said about cam belt changes I am guessing that your car has a diesel engine. If so, your car will be looking at a cam belt change at 10 years or 100,000 miles.
My s type Diesel has about 85,000 miles and 15 years but also with an engine change at a dealers error 12 years ago. I was advised by a first class mechanic who has been maintaining my cars for 20 years that my cam belt was in perfect condition after 12 years.
It could be that your car has a similar position so I would have a good mechanic look at your engine and make some advice after.
Regards,
Peter.
