Be careful about those bikes that have been ridden indoors. They get off easy in the braking dept, but dripping sweat can cause some rust. I bought a '82 Trek 614 that looks super clean, except that there's rust bubbling just above the bottom cup of the headset, and just around, behind the chainstay bridge, of all places. I've seen other trainer bikes for sale on the 'Bay that had much worse rust.

Yours may have escaped, it looks like a really sweet frame. There's a red one that parks outside the Starbuck's I frequent, and I look at it every time I walk out sipping my java.
