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)

The first destroyed alfa engine I saw was a 2.0 TS at alfaaid, failed due to the plastic tensioner had disintegrated. I hade a 75 2.0 TS at the time and after that was glad it was the older 8v with a chain driven cam.
Personally my GTA has done about 30k and 3 years old now, intend on changing the belt next year and certainly wouldn't risk 5yrs 72k.
