how long does a new beetle timing belt last?

I'd like to buy a used new beetle , what on average does the timing belt need to be replaced, mileage wise? and what milage on average does a timing belt start making noise or does the belt make noise before breaking? thanx

If I were buying a used New Beetle and was unsure of the condition and mileage of the belt then I would replace the belt and consider it cheap insurance. They will make no noise before breaking!. I think in Australia the agents say to replace the timing belt before 100,000km, however previously on this forum I've seen figures of between 80 to 100,000miles (not km) talked about. They also replace the waterpump at the same time as it is part and parcel.

i would change at 60 but thats even pushing it.
I would make sure that the water pump has been changed. this is a must!
If it hasnt been done, doit immediatly!
