How many years should a commercial elliptical trainer last (Life Fitness 9500 front drive unit)?

I have the option of buying a 10yr old Life Fitness 9500 front drive unit elliptical from a resale supplier (bought it off of a gym or college). I am unsure how long these commercial ellipticals typically last, so I don't know if buying a 10yr old elliptical is a wise decision. Help! How many years should a commercial elliptical trainer last (Life Fitness 9500 front drive unit)?It depnds on howmuch they were used and how good the care on them was, if they were regularly maintained they probably have another 10 years in them
