2002 Saturn SL1 When to replace struts?

I would only replace the struts when they fail they last a long time I have over 200,000 miles on my 99 saturn sl2 and my sister has over 200,000 miles on her 93 Saturn sl1 and the struts have never been changed and are still working great.I haven't replace many struts on the S model Saturn for failure and I have worked for staurn repairing cars for over 16yrs so if there not giving you trouble I would leave them alone.Spend your money on something your car needs.

Thanks for your reply.
