1987. As for value, it can vary. Cleaned up and well presented, you may be surprised what these little buggers can fetch. The best/worst thing you have going for you is the Miami Vice-ness. It can bring more than most other color Ironman bikes, or it can bring less. It just depends on if the right person finds it for sale at the right time. I, myself, love them and think there's not much more you can ask for. If anyone disagrees, funk 'em. They should get to kickin' pebbles.
What's generic about the Nitto stem, B115 bars and 27.0 Sugino fluted seatpost btw?
