Average life of PT Cruiser timing belt ?

I march to a different drum. Rubber belts and hoses are replaced at 4 years or 60 thousand miles. Just slight water and/or oil leaks will shorten the life of a belt exponentially.
My practice is expensive. The 96 Camry gets 2 idlers, water pump, and oil pump, along with the timing belt. It has like 238 thousand miles on it too.
