No, I have never had to change the starter. It should not be that hard. I had mine for 127k and it's on my ZE after the transplant. I was going to replace it but as I recall they were really expensive.
Mine broke down just after I bought the car, right after about driving 30 miles, i got of the highway forgot to put the clutch in, and the car stalled and i couldn't turn it on again, you can notice that its going bad if you are having trouble starting it, specially if its cold.
