I wouldn't say to compare a used, old 103R with a newly broken-in 103SA is meaningless. But an old cart would be absolutely inferior in performance than its hay day when it is still young.
Styli are subject to tear and wear? I believe so. But if used properly, a NATURAL diamond stylus would certainly last longer than the damping material & suspension of a cart. It is not uncommon when the suspension of a cart starts to degrade rapidly after a certain period of time while its stylus still remains sound & intact.
IME, no matter how high the prices of the carts, being too dry or too humid, with abrupt temperature fluctuations, air too salty near the ocean and direct sunlight, etc, would all accelerate the aging process of a cart and thus shorten its normal lifespan.
