I have my father in law's 1980 Competition GS and I am trying to find a good home for it. He is an engineer and meticulous by nature so to say he babied this bike would be a understatement. I am fairly certain it is a 25 1/2 inch frame. All parts on the bike are original except for possibly the saddle.
I am trying to find out what a fair value is for this bike. We are more interested in selling it to someone who would appreciate it, restore it, and ride it rather than make a big profit.
I posted some pictures here

Any help you can provide would be appreciated.
