every 80k is safe make sure to change the belt tentioners and check for oil leaks. Learned this the hardway...I bought the car and saw it was changed only 30k ago so I figued I was good for a while. Low and behold it broke going 70 on the highway. I did the timing belt part my self and found the tentioners were old and not working properly and there was a small oil on that side. Got the timing belt on and low and behold my compression was no where to be found because all my valves were busted. It sucked and it cost alot of money.
