I believe that year ('02 model though built in '01) had the old stainless sprockets for the Mirage Drive -- very strong, rugged Drive, but should be kept within chain tension limits (easy periodic adjustment). All Drive components are upgradable / rebuildable if necessary (although not all with the original parts) so it's not obsolete by any means. The Classics were virtually unchanged from
about '00 to '05 -- the very earliest few (late '90's) were fiberglass and the latest '06 model (last year made) got a few minor cockpit upgrades. So the difference between an '02 and an '03 is negligible.
An excellent, efficient and fun kayak. With (upgradable) Turbofins it's very spunky! The only capability the Classic doesn't have is a sailing ability (all current models do). It lacks a few of the current conveniences which is no big deal. I thoroughly enjoyed mine for many years!
