Thanks for all the great replies.
The 1991 looks pretty close, but it looks like someone has altered the paint job on the craigslist bike (no red stripe on the top bar, grey paint lines straight not slanted). I'm not sure why they would do that.
We're going to take a look this evening, and I think I'll follow everyone's advice and grab it as long as the frame looks to be in good shape. Is adding a couple chainrings, front derailleur, and a second shifter a difficult job for a beginner like me? Or is that something you'd take to a bike shop?
I really like those trekking bars bikemig, very cool. I'll probably try to find similar ones. I've never liked drop bars, even on my old road bike.
