How often do timing belts on cars actually fail, especially those that are just a year or two beyond their recommended replacement age?

Funny you should ask this question. A friend of mine recently imported a 25 year old Caterham from England. Before shipping, he sent it to the Caterham factory for a going over. He opted out of spending the money for a new timing belt.
If you know what a Caterham is, you know that most people drive them pretty much full on. His belt broke the other day. The engine is a GM based OHC four cylinder. Cost to repair: $2500 (yes, it is an interference engine, and every valve is bent). If he had had it done at the factory, it probably would have cost about $200.
Part two:
Many years ago I bought a 1990 Ford Probe. The factory recommended interval for changing the timing belt was 50,000 miles. I followed this religiously, even though I could discern no difference between the old belt and the new one. Result: 300,000 miles with the original engine, before I gave the car to a family who needed one.
Hope this helps you make the right decision.
