I think there is a formula for priceing. Research the cost of the model when new/since it's used, deduct 2 thirds-get the inflation factor off line and multiply by that. Usually works until you get into the collectible range. [pre 1975] Bike flippers round here (the ones in the biz) I find unreasonable price wise; and very UN customer friendly. Meanwhile all the garage sale bikes are snatched up. Can't afford used anymore! Such is life in the fast lane......
