You have misread or misinterpreted the date codes. The components are from 1986-1987. The bicycle is a good match for the 1987 model. FYI, original price was $695 US. Current value will depend on the local market conditions and the mechanical and cosmetic condition. The last looks very good, so I'd assume the same for the mechanical condition. You should certainly fetch the price range mentioned by Jet. If you're in a large market, I'd mark the price higher, $250-$300. Can I bother you for the serial number? TIA.
