Given what I'm seeing, $350. But that's the bottom of where I'd expect anyone to get to and I'm a cheapskate if it's not a brand I lust over. I also think $500 is the just north of high of where I'd expect this to sell at, which is $450. Mostly because based on tires, hoods and tape, this needs at least $100 in supplies to refurb back to riding condition, or $250 if you have a shop do the work. The (apparent) Modolo hoods are unobtanium.

Fair walkaway is $400 given the (apparently) exceptional condition. This isn't a 770, which would fetch $500 easy in this shape, or a 170, which would fetch $900 easy in this shape. I had a mid-80s 660 and 760 or two over the years. Really wasn't comfortable for me, came off as a little twitchy. But I'm sure there are people out there who love these.
