More concerned about the parts and condition,but there are a few cases where it matters. My old Dahon Mu SL folder was the last year that had the curse from God Pantour front hub;prolly wouldn't have bought it if I'd known about it in advance. Also,although I got a good deal on my '04 Pt Reyes,and really like it,would've been nice to get a '05 for the carbon fork.
