I have a 1985 660 that I got on CL about 2 weeks ago. I got it as a frame set and am almost finished with the build but I threw on my fixed gear parts just to try it and It's awesome. It has more race like geo than a 412.
From what I have read you can't go wrong with a steel frame Trek, no matter which model. If the frame is your size and you don't pay too much then snag the thang.

That's good that you can do a local pick up. I have bought things off the bay with p/u that wouldn't have made sense otherwise.

PS. I got my frame/fork/ headset for $100, in very good condition. Zero rust, minor paint nicks.
