Cambelt on my Boxer snapped at around 30,000 miles, in 2018 on a 2004 vehicle, when in the possession of a previous owner. The bill for the engine rebuild was in the document pack I inherited. There's a school of thought that maintains that commercial vehicles designed to be thrashed every day do not take well to being parked up idle for most of the time, and it's the tyres and cambelts that can deteriorate.
Had mine replaced earlier this year, and will be sticking to five year intervals irrespective of mileage.
