If you're looking to sell it, the best way is to do yourself whatever work is required to be able to sell the bike in a legitimately ready to ride state... If the bike is close to that as it sits. Cables, housing, bar tape, tires. Under 100 bucks. Clean bike, tune bike, sell bike. Bikes that don't need work to be ridden sell more quickly and for more money than bikes that need work to be ridden. If you don't want to do the work, sell it as is for what you can get... You can't make money paying shop labor rates.
If you're planning to ride it, older Treks are fantastic bikes. There isn't a quality road bike made since about 1970 that is obsolete. Obsolescent, as equipped, yes, but that's not the same thing. There hasn't been any advancement since then that makes everything else worthless for general use. And, with the exception of disc brakes, all of the important ones are trivially easy to put on an older steel frame.
Yeah, you'll never get the 2-3 extra pounds out of the frame. But the bike will ride just as nicely as it did in the 80s, it'll just work better. And, in the case of a vintage Trek, that's pretty nice.
