It does seem reasonable for what it is, but keep in mind it wouldn't be worth that if someone had done a 1x conversion, changed wheels, etc. It's only worth that because it's all original. Don't eff it up.

I'm with t2p - I would lean toward keeping it as original as possible. But then I'm someone that has toured many thousands of miles on a 3x6 setup (Trek 720) and I definitely appreciate the granny gear. Front derailleurs are pretty much "set it and forget it" and don't require much maintenance after the initial setup. And I still ride the hell out of my 3x6 Trek Elance. My Fuji is only 2x6 and that's actually enough gears too, even without the granny gear. I think people have too much of an obsession with how many gears their bike has. The 18 speeds on your Colnago were just fine then, for any type of riding someone might want to do, and it's still fine now.
