I have a creak in my saddle when rocking side to side (exaggerates it) that's starting to bug me. I tried grease and wax lube in the rail to saddle shell interface with no luck. There is movement between the rails and the plastic interface to the saddle. Don't know if it's wear or supposed to do that. Saddle is 14 years old. Otherwise I've been happy with it

Is the saddle toast and time to get a new one? (My buddy says it is, I'm being cheap and cautious)

Its the original saddle that came with my 2007 Specialized Roubaix
