That is when Mazda recommends the timing belt be changed. Everybody usually changes the water pump right away since you are right there at it it. Some people have had problems with the timing belt earlier, and others are 50,000+ miles past due to change... its a ll luck (or lack there of).
If the timing belt hasn't been changed yet, try that as a talk down point on the price.
