Recent evidence indicates that this particular brand of timing belt has a usable life of about 135,000 miles, somewhat less the 200,000 miles life typical of standard timing belt. Although the same model of timing belt has been used for both models of cars, the incidence of timing belt failure is considerably higher in the AG-75 than in the T-300. This is most likely because ______________________
