My local mechanic/garage owner said that cambelt failure was most common by far on the T-sparks, and the primary cause of it was that the tensioners on the T-sparks were crap!
Basically he said they were very poorly secured (I think he used the term "falling off") , and this was not an issue on the V6's.
In his experience at least V6 belt failure was very rare, although I certainly would not wait the 72000km myself.
(I don't have enough details myself to give a list)
Cheers,
