Please pardon me if this is an old issue, but:

The manual for my '96 850 says replace the timing belt at 70K mi. the odomoter reads 63. My mechanic, however, told me about a customer with an earlier model whose belt failed catastrophically a couple of thousand shy of the mileage spec, but got zilch from VCNA because the car was 6 or 7 years old.

Does this comport with reality? Should I replace my belt now?

Thanks in advance.
