I did my first t-belt assembly change at 86k miles. I am going to be doing it again as soon as I come back from vacation. (I have all the parts waiting for me at home). I have 135k right now. I am changing it at 60k only because I have an unidentifiable belt squeal somewhere and to replace only certain belts and pulleys makes no sense; when I would have to go back in and do more work in 15-20k more miles..

This car made my hair go gray, and did not care.
